libstdc++: Remove redundant return statement after static_assert(false)

Jakub's fix for PR c++/91388 means that we don't need an unreachable
return statement after static_assert(false).

libstdc++-v3/ChangeLog:

	* include/bits/atomic_wait.h (__wait_args::_M_setup_wait):
	Remove unreachable return statement.
