[PATCH] fm10k_main.c: fix missing return value check of alloc_skb()

Function fm10k_init_module() defined in drivers/net/ethernet/intel/fm10k/fm10k_main.c calls alloc_workqueue() to allocate memory for struct workqueue_struct which is dereferenced immediately. As alloc_workqueue() may return NULL on failure, this code piece may cause NULL pointer dereference
