sys_recv() merely expands the parameters to __sys_recvfrom() by NULL and NULL. Open-code this in the two places which used sys_recv() as a wrapper to __sys_recvfrom(). This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
