null_blk: add configfs variable shared_tags
Allow setting shared_tags through configfs, which could only be set as a
module parameter. For that purpose, delay tag_set initialization from
null_init() to null_add_dev(). Refer tag_set.ops as the flag to check if
tag_set is initialized or not.
The following parameters can not be set through configfs yet:
timeout
requeue
init_hctx
