xfs: refactor "does this fork map blocks" predicate
Replace the open-coded checks for whether or not an inode fork maps
blocks with a macro that will implant the code for us. This helps us
declutter the bmap code a bit.
Note that I had to use a macro instead of a static inline function
because of C header dependency problems between xfs_inode.h and
xfs_inode_fork.h.
Conversion was performed with the following Coccinelle script:
