RDMA/hfi1: Fix kernel pointer leak

[ Upstream commit 7d5cfafe8b4006a75b55c2f1fdfdb363f9a5cc98 ]

Pointers should be printed with %p or %px rather than cast to 'unsigned
long long' and printed with %llx.  Change %llx to %p to print the secured
pointer.

Fixes: 042a00f93aad ("IB/{ipoib,hfi1}: Add a timeout handler for rdma_netdev")
