Seems that there is a null-pointer de-reference in ufs/ufs_quotas.c
when the back pointer is being set for the nth time.

The source for -current's ufs_quotas.c looks slightly different than
2.2.2's (more usage of the TAILQ stuff), so it makes it hard to compare
the sources.  Any comments about what should really change in 2.2.2
besides a check for the null-pointer dereference?
