[PATCH 4/5] staging: r8188eu: read aid from struct ieee80211_mgmt

[Martin Kaiser]

Read the aid of the association response message from struct
ieee80211_mgmt instead of parsing the message ourselves.

Remove the cast to int, aid is a u16.
Keep the 0x3fff mask that is currently applied to the aid.
