RDMA/cxgb4: Fix null pointer dereference on alloc_skb failure
Currently if alloc_skb fails to allocate the skb a null skb is passed to
t4_set_arp_err_handler and this ends up dereferencing the null skb. Avoid
the NULL pointer dereference by checking for a NULL skb and returning
early.
Addresses-Coverity: ("Dereference null return")
Fixes: b38a0ad8ec11 ("RDMA/cxgb4: Set arp error handler for PASS_ACCEPT_RPL messages")
