[ Upstream commit b60cac14bb3c88cff2a7088d9095b01a80938c41 ]
With the dropping of the IOPOLL checking in the per-opcode handlers, we inadvertently left two checks in the recv/recvmsg and send/sendmsg prep handlers for the same thing, and one of them includes addr2 which holds the flags for these opcodes.
Fix it up and kill the redundant checks.
