Jan Höppner 709192d531 s390/dasd: Fix zero write for FBA devices 
A discard request that writes zeros using the global kernel internal
ZERO_PAGE will fail for machines with more than 2GB of memory due to the
location of the ZERO_PAGE.

Fix this by using a driver owned global zero page allocated with GFP_DMA
flag set.

Fixes: 28b841b3a7cb ("s390/dasd: Add discard support for FBA devices")
