PR libstdc++/54075
* include/bits/hashtable.h
(_Hashtable<>::_Hashtable(_InputIterator, _InputIterator,
size_type, ...): Remove std::max usage to guarantee that hashtable
state is consistent with hash policy state.
(_Hashtable<>::rehash): Likewise. Set _M_prev_resize to 0 to avoid
the hashtable shrinking on next insertion.
