[PATCH] s390: don't pad cdl blocks for write requests
The first blocks on a cdl formatted dasd device are smaller than the blocksize
of the device. Read requests are padded with a 'e5' pattern. Write requests
should not pad the (user) buffer with 'e5' because a write request is not
allowed to modify the buffer.
