xfs: remove bc_btnum from btree cursors

From Christoph Hellwig,

This series continues the migration of btree geometry information out of
the cursor structure and into the ops structure.  This time around, we
replace the btree type enumeration (btnum) with an explicit name string
in the btree ops structure.  This enables easy creation of /any/ new
btree type without having to mess with libxfs.
