user32: Add the SW_SHOWDEFAULT case to WINPOS_MinMaximize().

[Dmitry Timoshkov]

This patch fixes the 1st problem reported in the bug 26017.
Pinball creates its main window with WS_MAXIMIZE style set, then calls
ShowWindow(SW_SHOWDEFAULT). show_window() handles SW_SHOWDEFAULT same
way as it does for SW_RESTORE/SW_SHOWNORMAL, but WINPOS_MinMaximize()
misses the SW_SHOWDEFAULT case.
