Vanou Ishii 7217c6d1d1 Rescan device after filesystem creation
In work_on_disk function, IPA runs mkfs commands without
following device rescan operation. This leads to incorrect
content of uuids_to_return to be returned.
These mkfs commands modify partition label but IPA fails
to catch such changes because of no following device
rescan operation.

This commit adds call of device rescan function before
uuids_to_return construction.
