net: socket: replace call to sys_recv() with __sys_recvfrom()
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.

Miller <davem@davemloft.net> Cc: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
