nax: Avoid unnecessary calls to AsNCA() in IdentifyType()

Browse source 
AsNCA() allocates an NCA instance every time it's called. In the current
manner it's used, it's quite inefficient as it's making a redundant
allocation.

We can just amend the order of the conditionals to make it easier to
just call it once.
