scsi: snic: Return error code on memory allocation failure
If a call to mempool_create_slab_pool() in snic_probe() returns NULL, return -ENOMEM to indicate failure. mempool_creat_slab_pool() only fails if it cannot allocate memory. https://bugzilla.kernel.org/show_bug.cgi?id=189061 Reported-by: bianpan2010@ruc.edu.cn Signed-off-by: Burak Ok <burak-kernel@bur0k.de> Signed-off-by: Andreas Schaertl <andreas.schaertl@fau.de> Acked-by: Narsimhulu Musini <nmusini@cisco.com> Reviewed-by: Ewan D.
