x86/syscalls: Fix -Wmissing-prototypes warnings from COND_SYSCALL()
Building kernel/sys_ni.c with W=1 emits tons of -Wmissing-prototypes warnings:
$ make W=1 kernel/sys_ni.o
[ snip ]
CC kernel/sys_ni.o
./arch/x86/include/asm/syscall_wrapper.h:83:14: warning: no previous prototype for '__ia32_sys_io_setup' [-Wmissing-prototypes]
...
The problem is in __COND_SYSCALL(), the __SYS_STUB0() and __SYS_STUBx() macros
defined a few lines above already have forward declarations.
Let's do likewise for __COND_SYSCALL() to fix the warnings.
