arm: Use the target EL state when determining fault format
We currently check the current state instead of the state of the target EL when determining how we report a fault. This breaks interprocessing since EL0 in aarch32 would report its fault status using the aarch32 registers even if EL1 is in aarch64. Fix this to report the fault using the format of the target EL.
