[PATCH] zswap: do not allocate from atomic pool

[Sergey Senozhatsky <senozhatsky@xxxxxxxxxxxx>]

zswap_frontswap_load() should be called from preemptible
context (we even call mutex_lock() there) and it does not
look like we need to do GFP_ATOMIC allocaion for temp
buffer there. Use GFP_KERNEL instead.
