kprobes/arm: Fix ldrd/strd emulation

Currently emulate_ldrd and emulate_strd don't even have the adjustment
of the PC value, so in case of Rn == PC, it will not update the PC
incorrectly but instead load/store from the wrong address.  Let's add
both the adjustment of the PC value and the check for PC == PC.
