Colin Ian King 9754bab205 RDMA/cxgb4: Fix null pointer dereference on alloc_skb failure

[ Upstream commit a6d2a5a92e ]

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: b38a0ad8ec ("RDMA/cxgb4: Set arp error handler for PASS_ACCEPT_RPL messages")
