fsck_ffs fix
Proposed patch, satisfies the previously provided reproducer.
The segfault was being hit in ckfini() (sbin/fsck_ffs/fsutil.c) while
attempting to traverse the buffer cache.
The tail queue used for the buffer cache isn't initialized before dropping into
gjournal_check().
The buffer cache appears to be unused when doing an `fsck_ffs -p` on a
gjournaled filesystem.
