[PATCH] xl: fix xl cpupool-list <poolid>

Hi,

the help screen of xl cpupool-list promises to allow a CPU pool to
be named on the command line, which will then be listed only.
Probably caused by a "DeMorgan brain twist" this specific CPU pool
is _omitted_ instead. The patch fixes this, so single CPU pools
can be explicitly listed again.

Regards,
Andre.
