target/ppc: Don't update radix PTE R/C bits with gdbstub
gdbstub shouldn't silently change guest visible state when doing address
translation. Since the R/C bits can only be updated when handling a MMU
fault, let's reuse the cause_excp flag and rename it to guest_visible.
While here drop a not very useful comment.
This was found while reading the code. I could verify that this affects
both powernv and pseries, but I failed to observe any actual bug.
