zed: misc vdev_enc_sysfs_path fixes

Browse Source 
There have been rare cases where the VDEV_ENC_SYSFS_PATH value that zed
gets passed is stale.  To mitigate this, dynamically check the sysfs
path at the time of zed event processing, and use the dynamic value if
possible.  Note that there will be other times when we can not
dynamically detect the sysfs path (like if a disk disappears) and have
to rely on the old value for things like turning on the fault LED.  That
is to say, we can't just blindly use the dynamic path in every case.

Also:
	- Add enclosure sysfs entry when running 'zpool add'
	- Fix 'slot' and 'enc' zpool.d scripts for nvme
