* Initialize all static mutexes in the kernel through a MUTEX_INITIALIZER()

and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
  As they are all initialized statically through the MUTEX_INITIALIZER() now
  this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
  remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.
