Guangguan Wang 8d75d66ff1 net/smc: non blocking recvmsg() return -EAGAIN when no data and signal_pending ...

[ Upstream commit f3c46e41b32b6266cf60b0985c61748f53bf1c61 ]

Non blocking sendmsg will return -EAGAIN when any signal pending
and no send space left, while non blocking recvmsg return -EINTR
when signal pending and no data received. This may makes confused.
As TCP returns -EAGAIN in the conditions described above. Align the
behavior of smc with TCP.
