xfs: simplify the fallocate path
Call xfs_alloc_file_space or xfs_free_file_space directly from xfs_file_fallocate instead of going through xfs_change_file_space. This simplified the code by removing the unessecary marshalling of the arguments into an xfs_flock64_t structure and allows removing checks that are already done in the VFS code.
