xfs: Validate atomic writes
Validate that an atomic write adheres to length/offset rules. Currently
we can only write a single FS block.
For an IOCB with IOCB_ATOMIC set to get as far as xfs_file_write_iter(),
FMODE_CAN_ATOMIC_WRITE will need to be set for the file; for this,
ATOMICWRITES flags would also need to be set for the inode.
