iwlwifi: pcie: add rx packet sequence number to dbg print

For each RX packet until this patch there only was a debug
print of the HCMD and the offset. This adds also the
sequence number of the packet for easier matching between
what was sent, what came back / was received, and what
got stuck somewhere and was never responded by the FW.
