IB/hfi1: Error path MAD response size is incorrect
[ Upstream commit 935c84ac649a147e1aad2c48ee5c5a1a9176b2d0 ]
If a MAD packet has incorrect header information, the logic uses the reply
path to report the error. The reply path expects *resp_len to be set
prior to return. Unfortunately, *resp_len is set to 0 for this path.
This causes an incorrect response packet.
Fix by ensuring that the *resp_len is defaulted to the incoming packet
size (wc->bytes_len - sizeof(GRH)).
