staging: r8188eu: Associate pointer symbol with parameter name

The pointer symbol '*' should be associated with the function parameter
name and not its type. This improves code readability and adheres to the
coding-style guidelines. Address following checkpatch reported error:
	ERROR: "foo *   bar" should be "foo *bar"

While in there, update parameter name at one place to match other function
declarations.
