[PATCH v2] cmdPerf: Display enabled/disabled message on perf event enable/disable

[Nitesh Konkar <niteshkonkar.libvirt@xxxxxxxxx>]

Currently no message is displayed on successful
perf event enable or disable. This patch gives
the enabled/disabled status message on successful
enabling/disabling of the perf event.
Eg:virsh perf Domain --enable instructions --disable cache_misses
instructions   : enabled
cache_misses   : disabled
