mutex: Make mutex_destroy() an inline function

Browse source 
The non-debug variant of mutex_destroy is a no-op, currently
implemented as a macro which does nothing. This approach fails
to check the type of the parameter, so an error would only show
when debugging gets enabled. Using an inline function instead,
offers type checking for earlier bug catching.
