filter-usable: filter out blocked and suspended devices firmly when scanning for lvmetad

Browse Source 
We can't hang on blocked or suspended devices when the scan is done
for lvmetad update - when the device gets unblocked or resumed, there's
always CHANGE event generated which will fire the udev rule to run
extra pvscan --cache for that device which makes sure that lvmetad
is up-to-date.
