util: Improve os_mem_prealloc error message
Currently, when the preallocating guest memory process fails, a not
so helpful error message is printed out:
# virsh start migt10
error: Failed to start domain migt10
error: internal error: process exited while connecting to monitor:
os_mem_prealloc: failed to preallocate pages
From the error message it's not clear at the first glance where the
problem lies. However, changing the error message might give users a
clue.
