What is the change?
- Fixes#83660 allowing device to now enter suspend mode even if
CONFIG_DEBUG_THREAD_INFO is enabled.
Why is this needed?
- z_sys_post_kernel was cleared as part of #d778d5c
to "allow debuggers to display the correct thread state after
the first 3 instructions have run".
This is not required while resuming from suspend and
it prevents the device from entering suspend so,
move it out of resume path.
