Lioncash 45195a51a7 nax: Avoid re-parsing NAX data with GetFileType()
An instance of the NAX apploader already has an existing NAX instance in
memory. Calling directly into IdentifyType() directly would re-parse the
whole file again into yet another NAX instance, only to toss it away
again.

This gets rid of unnecessary/redundant file parsing and allocations.
