libafs: update the volume setup time when the vldb is rechecked

The vldb is rechecked when the fileserver returns certain error codes,
such as VMOVED.  When the vldb is rechecked, update the volume
setupTime to reflect the most recent time the volume vldb information
is known to be correct.

Be sure the VRecheck flag is cleared after checking the vldb, since
the volume write lock was dropped after finding the volume.
