This logs at VIR_LOG_ERROR if level is ever out of range (not one of the
3 defined virErrorLevel values).  Can we ever get virErrorLevel set from
external input, or would an out-of-range enum value represent a bug in
our code?  If the former, then it may still be worth keeping this
function, and only mapping the three known levels to VIR_LOG_INFO while
keeping all other values as VIR_LOG_ERROR.  If the latter, then this
patch seems fine to me.
