  GlobalISel: Fix using wrong calling convention for callees

This was taking the calling convention from the parent function,
instead of the callee. Avoids regressions in a future patch when the
caller and callee have different type breakdowns.

For some reason AArch64's lowerFormalArguments seems to intentionally
ignore the parent isVarArg.
