KVM: arm64: Change kvm_handle_mmio_return() return polarity

Most exit handlers return <= 0 to indicate that the host needs to
handle the exit. Make kvm_handle_mmio_return() consistent with
the exit handlers in handle_exit(). This makes the code easier to
reason about, and makes it easier to add other handlers in future
patches.

No functional change intended.
