arm64: use the correct function type in SYSCALL_DEFINE0

[ Upstream commit 0e358bd7b7ebd27e491dabed938eae254c17fe3b ]

Although a syscall defined using SYSCALL_DEFINE0 doesn't accept
parameters, use the correct function type to avoid indirect call
type mismatches with Control-Flow Integrity checking.
