wic: use the same partition object in direct and partitionedfs
Partition attributes were copied to the dictionary in partitionedfs code, which makes the code hard to follow. Used partition object passed from direct.py module as is in partitionedfs. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
