net: socket: fix potential spectre v1 gadget in socketcall
commit c8e8cd579bb4265651df8223730105341e61a2d1 upstream.
'call' is a user-controlled value, so sanitize the array index after the
bounds check to avoid speculating past the bounds of the 'nargs' array.
Found with the help of Smatch:
net/socket.c:2508 __do_sys_socketcall() warn: potential spectre issue
'nargs' [r] (local cap)
