tangzhenhao f87905660e drivers/lightnvm: fix a null-ptr-deref bug in pblk-core.c
At line 294 in drivers/lightnvm/pblk-write.c, function pblk_gen_run_ws is
called with actual param GFP_ATOMIC. pblk_gen_run_ws call mempool_alloc
using "GFP_ATOMIC" flag, so mempool_alloc can return null. So we need to
check the return-val of mempool_alloc to avoid null-ptr-deref bug.
