[PATCH blktests 2/2] loop/006: settle udev before completing the test

[Sebastian Chlad <sebastianchlad@gmail.com>]

Ensures udev has processed the burst of attach/detach/LOOP_CHANGE_FD
activity generated by this test before control is handed back, so it
does not leave a backlog for the next test to contend with.
