filter: do not check for suspended devs in filter-usable in lvmetad mode

Browse Source 
We already do check for suspended devs within udev rules where
the pvscan is to update lvmetad. So the check for suspended devs
in "pre-lvmetad" chain is not useful here - remove it - it may
be a source of hardly to detect races anyway (if udev rule detects
the device is not suspended and then the pvscan instance sees the
dev as suspended, we may end up not reacting to the event properly).
