IB/hfi1: Check P_KEY for all sent packets from user mode Add the P_KEY check for user-context mechanism for both PIO and SDMA. For PIO, the SendCtxtCheckEnable.DisallowKDETHPackets is set by default. When the P_KEY is set, SendCtxtCheckEnable.DisallowKDETHPackets is cleared. For SDMA, a software check was included. This change requires user processes to set the P_KEY before sending any packets, otherwise, the sent packet will fail. The original submission didn't have this check but it's required.
