kernel: fix sometimes sucompat can not toggle by manager (#2484)

Browse Source 
When the manager is already running, if other programs / kernel toggle
the sucompat enable status,
The manager "Disable SU Compat" toggle button can not work, kmesg print
"cmd enable su but no need to change."

I think we should still return reply_ok when the syscall value is
consistent with the kernel, which would fix the issue.
