Tom Caputi cef48f14da Remove races from scrub / resilver tests
Currently, several tests in the ZFS Test Suite that attempt to
test scrub and resilver behavior occasionally fail. A big reason
for this is that these tests use a combination of zinject and
zfs_scan_vdev_limit to attempt to slow these operations enough
to verify their test commands. This method works most of the time,
but provides no guarantees and leads to flaky behavior. This patch
adds a new tunable, zfs_scan_suspend_progress, that ensures that
scans make no progress, guaranteeing that tests can be run without
racing.

This patch also changes zfs_remove_max_bytes_pause to match this
new tunable. This provides some consistency between these two
similar tunables and ensures that the tunable will not misbehave
on 32-bit systems.
