xfs: refactor the inode fork memory allocation functions

Hoist the code that allocates, frees, and reallocates if_broot into a
single xfs_iroot_krealloc function.  Eventually we're going to push
xfs_iroot_realloc into the btree ops structure to handle multiple
inode-rooted btrees, but first let's separate out the bits that should
stay in xfs_inode_fork.c.
