RISC-V: Fix PLIC pending bitfield reads

The address calculation for the pending bitfield had
a copy paste bug. This bug went unnoticed because the Linux
PLIC driver does not read the pending bitfield, rather it
reads pending interrupt numbers from the claim register
and writes acknowledgements back to the claim register.
