On error dsl_prop_get_all_ds() does not free the nvlist it allocates.
This behavior may have been intentional when originally written
but is atypical and often confusing. Since no callers rely on this
behavior the function has been updated to always free the nvlist
on error.

- Fix autoreplace behaviour on statechange-led.sh script.
ZED sends the following events on an auto-replace:
1. statechange: Disk goes UNAVAIL->ONLINE
2. statechange: Disk goes ONLINE->UNAVAIL
3. vdev_attach: Disk goes ONLINE
Events 1-2 happen when ZED first attempts to do an auto-online. When that
fails, ZED then tries an auto-replace, generating the vdev_attach event in #3.
In the previous code, statechange-led was only looking at the UNAVAIL->ONLINE
transition to turn off the LED. It ignored the #2 ONLINE->UNAVAIL transition,
assuming it was just the "old" VDEV going offline. This is problematic, as
a drive can go from ONLINE->UNAVAIL when it's malfunctioning, and we don't want
to ignore that.
This new patch correctly turns on the fault LED every time a drive becomes
UNAVAIL. It also monitors vdev_attach events to trigger turning off the LED
when an auto-replaced disk comes online.

Previously when a drive faulted, the statechange-led.sh script would lookup
the drive's LED sysfs entry in /sys/block/sd*/device/enclosure_device, and
turn it on. During testing we noticed that if you pulled out a drive, or if
the drive was so badly broken that it no longer appeared to Linux, that the
/sys/block/sd* path would be removed, and the script could not lookup the
LED entry.
To fix this, this patch looks up the disks's more persistent
"/sys/class/enclosure/X:X:X:X/Slot N" LED sysfs path at pool import. It then
passes that path to the statechange-led script to use, rather than having the
script look it up on the fly. This allows the script to turn on/off the slot
LEDs even when the drive is missing.

test-runner should be creating the current symlink in the
directory above the output directory. In a previous commit,
the current symlink was placed in the current working

that the output directory is always accessible.
This is needed because without this there's no deterministic
way to get the path to ZFS Test Suite results until after the
test suite has started. This makes it difficult for buildbot to
follow the log file.

This was initially overlooked because the x86_64 implementation
