ublk: don't suggest CONFIG_BLK_DEV_UBLK=Y 



The CONFIG_BLK_DEV_UBLK help text suggests setting the config option to
Y so task_work_add() can be used to dispatch I/O, improving performance.
However, this mechanism was removed in commit 29dc5d06 ("ublk: kill
queuing request by task_work_add"). So remove this paragraph from the
config help text.
