When the discard length is not a multiple of RSXX_HW_BLK_SIZE, the
discard code will get into an infinite loop, even discarding data it is
not supposed to. This will also hang the system.
This can be reproduced by doing an ioctl BLKDISCARD to /dev/rsxx0 with
range from 0 to 1024.
That is a bug that should be fixed in the discard code, not worked
around in the driver.
