Bart Van Assche 1a8f4a4908 brd: Fix discard request processing ...

commit 5e4298be45e83ecdffaabb370eea9396889b07f1 upstream.

Avoid that discard requests with size => PAGE_SIZE fail with
-EIO. Refuse discard requests if the discard size is not a
multiple of the page size.

Fixes: 2dbe549576 ("brd: Refuse improperly aligned discard requests")
