arm64: use the correct function type for __arm64_sys_ni_syscall
[ Upstream commit 1e29ab3186e33c77dbb2d7566172a205b59fa390 ]
Calling sys_ni_syscall through a syscall_fn_t pointer trips indirect
call Control-Flow Integrity checking due to a function type
mismatch. Use SYSCALL_DEFINE0 for __arm64_sys_ni_syscall instead and
remove the now unnecessary casts.
