iov_iter: fix iov_iter_type
Commit 875f1d0769cd ("iov_iter: add ITER_BVEC_FLAG_NO_REF flag")
introduces one extra flag of ITER_BVEC_FLAG_NO_REF, and this flag
is stored into iter->type.
However, iov_iter_type() doesn't consider the new added flag, fix
it by masking this flag in iov_iter_type().
Fixes: 875f1d0769cd ("iov_iter: add ITER_BVEC_FLAG_NO_REF flag")
