qemuMonitorTextGetAllBlockStatsInfo: Fix line validation

Browse Source 
There's a bug in the function. We expect the following format for
the data we are parsing here:

  key: value

So we use strchr() to find ':' and then see if it is followed by
space. But the check that does just that is slightly incorrect.
