bcachefs: Reserve 8 bits in bch_reflink_p

Browse source

Better repair for reflink pointers, as well as propagating new inode
options to indirect extents, are going to require a few extra bits
bch_reflink_p: so claim a few from the high end of the destination
index.

Also add some missing bounds checking.
