Summary

In the USB subsystem, it is often difficult to determine which functions
require the lock context and which do not. To improve readability and
maintainability, all functions that require the lock context are
renamed with the _locked suffix. In addition, mtx_assert checks are
added to all non-static function and static functions used as function
pointers to sure the correct lock context is held.
