RDMA/amso1100: Add check for NULL reply_msg in c2_intr()
Fix a place where we might dereference a NULL pointer; this fixes Coverity CID 1392. On inspection I also found a place where we could attempt to kmem_cache_free() a NULL pointer, so fix this too. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
