Subject: [PATCH v2 1/5] staging: r8188eu: replace a get_da call

The r8188eu driver implements an internal get_da function to read the
destination address (da) from an incoming message. Callers of this
function should be updated to use the ieee80211 framework, with the goal
of removing get_da eventually.

This patch replaces a get_da call in the OnAssocRsp function.
