[hid_core] fix bounds-check aruid index in GetControllerFromNpadIdType (#4064)

GetIndexFromAruid returns AruidIndexMax as the “not found” value, but both
GetControllerFromNpadIdType overloads were using that value to index
controller_data without checking it first.

when a game routes through DisconnectNpad before its applet resource is
registered, we can end up indexing past the end of controller_data. That seems
to be what was crashing some games on launch, especially on macOS and Android,
where the out-of-bounds read is less likely to just slide by unnoticed.

So yeah, AruidIndexMax is a sentinel, not a real controller_data index, so we
should not treat it like one.
