Modified Files:
        src/sys/ufs/ffs: ffs_snapshot.c

Log Message:
ffs_copyonwrite(): stop abusing ffs_balloc() to get a block address.
Use ufs_getlbns()/bread() instead.
Saves some reads and removes deep recursion with possible deadlock
when ffs_balloc() runs copy-on-write on the buffer returned.
