loop: LOOP_SET_FD: send uevents for partitions

Browse Source 
commit 0dba7a05b9e47d8b546399117b0ddf2426dc6042 upstream.

Remove the suppression of the uevents before scanning for partitions.
The partitions inherit their suppression settings from their parent device,
which lead to the uevents being dropped.

This is similar to the same changes for LOOP_CONFIGURE done in
commit bb430b6942 ("loop: LOOP_CONFIGURE: send uevents for partitions").

Fixes: 498ef5c777 ("loop: suppress uevents while reconfiguring the device")
