[PATCH v5 04/17] s390/dasd: Use GFP_KERNEL in dasd_alloc_device()

[Stefan Haberland <sth@linux.ibm.com>]

dasd_alloc_device() runs in process context (device set_online), so its
pool allocations do not need GFP_ATOMIC. Use GFP_KERNEL instead, which is
more reliable, especially for the larger DMA allocations that later ESE
full-track work adds here.

No functional change intended.
