[Qemu-trivial] [PATCH] util: Improve os_mem_prealloc error message |

Currently, when the preallocating guest memory process fails, an 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 uses a
clue.
