[PATCH] staging: greybus: loopback: remove unused includes

[Batu Ada Tutkun]

linux/random.h, linux/sizes.h, linux/cdev.h, linux/fs.h, and
linux/workqueue.h are not used anywhere in this file; none of their
symbols appear in the source, and none are needed transitively either
(debugfs helpers come from linux/debugfs.h, the async worker uses
kthread_run()/kthread_stop() rather than the workqueue API).

Verified by removing the five includes and rebuilding
drivers/staging/greybus out-of-tree with W=1: no new warnings or
errors, and checkpatch.pl reports the same warning/check count before
and after.
