nbd: Return correct error for write to read-only export
The NBD Protocol requires that servers should send EPERM for
attempts to write (or trim) a read-only export. We were
correct for TRIM (blk_co_discard() gave EPERM); but were
manually setting EROFS which then got mapped to EINVAL over
the wire on writes.
