xfs: split out a btree type from the btree ops geometry flags
Two of the btree cursor flags are always used together and encode
the fundamental btree type. There currently are two such types:
1) an on-disk AG-rooted btree with 32-bit pointers
2) an on-disk inode-rooted btree with 64-bit pointers
and we're about to add:
3) an in-memory btree with 64-bit pointers
Introduce a new enum and a new type field in struct xfs_btree_geom
to encode this type directly instead of using flags and change most
code to switch on this enum.
