[PATCH] f2fs: remove submit label in __submit_discard_cmd()

[PATCH] f2fs: remove submit label in __submit_discard_cmd()

[Yangtao Li]

Complaint from Matthew Wilcox in another similar place:

	"submit?  You don't submit anything at the 'submit' label.
	it should be called 'skip' or something.  But I think this
	is just badly written and you don't need a goto at all."

Let's remove submit label for readability.

Thanks. I added {} to meet the coding style.
