Subject: [PATCH] blk-throttle: Do the new group initialization with the help
 of a function

Group initialization code seems to be at two places. root group
initialization in blk_throtl_init() and dynamically allocated group
in throtl_find_alloc_tg(). Create a common function and use at both
the places.
