If a kiocb or iomap_iter is available, then use the IOCB_WRITE flag or the
IOMAP_WRITE flag to determine whether we're writing rather than the
iterator direction flag.
This allows all but three of the users of iov_iter_rw() to be got rid of: a
consistency check and a warning statement in cifs and one user in the block
layer that has neither available.
