Change subject: installer: make sure data size could be setup "0"
......................................................................


Patch Set 2: Verified+1

Hey, Fabian

Previously tui could accept "0" as data_size,but if users want setup data_size as "0" to disable data partition, it will create data partition with remaining free space.It wasn't what we expect results.
This patch could disable data partition when setting data_size as "0"
