Add zfs_scan_ignore_errors tunable

Browse Source 
When it's set, a DTL range will be cleared even if its scan/scrub had
errors.  This allows to work around resilver/scrub upon import when the
pool has errors.

If set to a nonzero value, remove the DTL (dirty time list) upon
completion of a pool scan (scrub) even if there were unrepairable
errors. It is intended to be used during pool repair or recovery to
stop resilvering when the pool is next imported.
