block: return EPERM on writes or discards to read-only devices
This is the behavior in the operating system, for example Linux's blkdev_write_iter has the following: if (bdev_read_only(I_BDEV(bd_inode))) return -EPERM; This does not apply to opening a device for read/write, when the device only supports read-only operation. In this case any of EACCES, EPERM or EROFS is acceptable depending on why writing is not possible.
