Ian Munsie ae07f551c4 tracing/syscalls: Early terminate search for sys_ni_syscall ...

Many system calls are unimplemented and mapped to sys_ni_syscall, but at
boot ftrace would still search through every syscall metadata entry for
a match which wouldn't be there.

This patch adds causes the search to terminate early if the system call
is not mapped.
