locking/ww_mutex: Fix compilation of __WW_MUTEX_INITIALIZER
From conflicting macro parameters, passing the wrong name to
__MUTEX_INITIALIZER and a stray '\', #define __WW_MUTEX_INITIALIZER was
very unhappy.
One unnecessary change was to choose to pass &ww_class instead of
implicitly taking the address of the class within the macro.
