Clear vdev_faulted if ZPOOL_CONFIG_AUX_STATE is not set to "external"
ZoL supports "zpool export -f" (force fault), which can be combined
with "-t" (temporary fault; don't persist across export/import) and
causes a MOS configuration to be set with ZPOOL_CONFIG_FAULTED=1
and without ZFS_CONFIG_AUX_STATE set at all. In this case, the
previously-offlined vdev should be imported in an on-line state and.
Clearing the "vdev_faulted" flag causes the import to treat the
device as on-line. Typically, resilver will catch it up based on
its DTL.
