x86/syscalls: Stop filling syscall arrays with *_sys_ni_syscall

Browse source

This is a follow-up cleanup after switching to the generic syscalltbl.sh.

The old x86 specific script skipped non-existing syscalls. So, the
generated syscalls_64.h, for example, had a big hole in the syscall numbers
335-423 range. That is why there exists [0 ... __NR_*_syscall_max] =
&__*_sys_ni_cyscall.

The new script, scripts/syscalltbl.sh automatically fills holes
with __SYSCALL(<nr>, sys_ni_syscall), hence such ugly code can
go away. The designated initializers, '[nr] =' are also unneeded.

Also, there is no need to give __NR_*_syscall_max+1 because the array
size is implied by the number of syscalls in the generated headers.
Hence, there is no need to include <asm/unistd.h>, either.
