Unflags Usable by AI on ability if it adds a designated status. This routine is to prevent the AI from using unnecessary status adding abilities if they are not needed, such as Shell vs a team that has no Magic damage whatsoever.

r4 = Ability Address (In Unit Ability List) r5 = (0011(Float), 0026(Reflect), 001a(Protect), 001b(Shell), -1)
