Subject: [PATCH] cfq-iosched: remove unused 'group_changed' in
 cfq_service_tree_add()

The 'group_changed' variable is initialized to 0 and never changed, so
checking the variable is meaningless.

It is a leftover from 0bbfeb832042 ("cfq-iosched: Always provide group
iosolation."). Let's get rid of it.
