[S390] vmur: allocate single record buffers instead of one big data b…
…uffer vmur allocates one contiguous kernel buffer to copy user data when creating ccw programs for punch or printer. If big block sizes are used, under memory pressure it can happen, that we do not get memory in one chunk. Now we allocate memory for each single record to avoid high order allocations.
