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.
