3PAR enable multiattach capability reporting

This patch enables the reporting of the
multiattach capability in get_volume_stats.
The scheduler currently filters on the capability
for drivers that support/don't support that ability
to do more than one attachment for a volume.
By reporting multiattach = True, it lets the scheduler
know this driver allows attaching a volume more than once.
