loop: Add sanity check for read/write_iter
Some file systems do not support read_iter/write_iter, such as selinuxfs
in this issue.
So before calling them, first confirm that the interface is supported and
then call it.
It is releavant in that vfs_iter_read/write have the check, and removal
of their used caused szybot to be able to hit this issue.
Fixes: f2fed441c69b ("loop: stop using vfs_iter__{read,write} for buffered I/O")
