arm/arm64: KVM: avoid unnecessary guest register mangling on MMIO read
Currently we mangle the endianness of the guest's register even on an MMIO _read_, where it is completely useless, because we will not use the value of that register. Rework the io_mem_abort() function to clearly separate between reads and writes and only do the endianness mangling on MMIO writes.
