[PATCH 2/2] monitor/misc: Set current_cpu for memory dump

[Bin Meng]

When accessing the per-CPU register bank of some devices (e.g.: GIC)
from the monitor context, a segfault occurs. This is due to current_cpu
is not set, as the context is not a guest CPU.

Let's set current_cpu before doing the acutal memory dump.
