Fix a bug where resilver is not started automatically on pool import or load.

Browse Source 
If disk was missing on pool load or import and on next pool load or import
it was present, resilver wasn't started automatically and ZFS reported all disks
as ONLINE and healthy. Then, when another disk died, pool became unaccessible,
because if it was 2-way mirror or RAIDZ1 two vdevs were out of sync.

To fix the problem, start resilver automatically on pool load or import.
