[PATCH 2/6] staging: ks7010: Factor out code into helper methods.

[PATCH 2/6] staging: ks7010: Factor out code into helper methods.

[Quytelda Kahja]

Some cases in the switch statement in get_ap_information() are indented
as much as five levels, which makes the code difficult to read because
of all the wrapping.  Factor them out into helper methods.
