block: use blk_op_str() in blk-mq-debugfs.c
Now that we've a helper function blk_op_str() to convert the REQ_OP_XXX to string XXX, adjust the code to use that. Get rid of the duplicate array op_name which is now present in the blk-core.c which we renamed it to "blk_op_name" and open coding in the blk-mq-debugfs.c.
