This of course leads to the BUG halt in add_timer getting called. Fix seems pretty straightforward, just check before the timer is added if its already been started. If it has mod the timer instead to min(current expiration, new expiration) Its been tested but not confirmed to fix the problem, as the issue has only occured in production environments where test kernels are enjoined from being installed. It appears to be a sane fix to me though.

As discussed in the alternative approach zephyrproject-rtos/zephyr#68494, k_panic() in POSIX mode has various shortcomings that do not provide a useful trace. Useless pointers to signal handlers or other cleanup routines are printed instead. Leverage our already existing k_sys_fatal_error_handler() and dereference a NULL pointer there when in POSIX mode. This "fails fast" and provides a complete and relevant stack trace in CI when fuzzing or when using some other static analyzer. Example of how fuzzing failure thesofproject#8832 would have looked like in CI results thanks to this commit: ``` ./build-fuzz/zephyr/zephyr.exe: Running 1 inputs 1 time(s) each.

The fuzzer engine has produced crash caused by NULL pointer read that
originated from ipc_stream_pcm_free(). The crash happens when the
pipeline of the found comp_dev does not have a source_comp and
pipeline_reset() is called for it. This commit simply adds a test
for such a situation and bails out if it is found.
