Code Issues Proposed changes

Fix CapacityFilter to accept None volume type 

Change I8b43624b934fadf1036fafa1f5e2b94b5317f81c introduced reading
volume_type['extra specs'] from filter_properties in CapacityFilter
without taking into account that volume_type can be None (when
default_volume_type is not set in cinder.conf). This commit fixes that.
