io_uring/cmd: fix breakage in SOCKET_URING_OP_SIOC* implementation

	In 8e9fad0e "io_uring: Add io_uring command support for sockets"
you've got an include of asm-generic/ioctls.h done in io_uring/uring_cmd.c.
That had been done for the sake of this chunk -
+               ret = prot->ioctl(sk, SIOCINQ, &arg);
+               if (ret)
+                       return ret;
+               return arg;
+       case SOCKET_URING_OP_SIOCOUTQ:
+               ret = prot->ioctl(sk, SIOCOUTQ, &arg);

SIOC{IN,OUT}Q are defined to symbols (FIONREAD and TIOCOUTQ) that come from
ioctls.h, all right, but the values vary by the architecture.

FIONREAD is
	0x467F on mips
	0x4004667F on alpha, powerpc and sparc
	0x8004667F on sh and xtensa
	0x541B everywhere else
TIOCOUTQ is
	0x7472 on mips
	0x40047473 on alpha, powerpc and sparc
	0x80047473 on sh and xtensa
	0x5411 everywhere else

->ioctl() expects the same values it would've gotten from userland; all
places where we compare with SIOC{IN,OUT}Q are using asm/ioctls.h, so
they pick the correct values.  io_uring_cmd_sock(), OTOH, ends up
passing the default ones.
