[ 63/64] mwifiex: complete last internal scan

[Greg Kroah-Hartman]

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bing Zhao <bzhao@xxxxxxxxxxx>

commit 21de979ecfc7b7f9442f8aea9a54b3ab670d0151 upstream.

We are waiting on first scan command of internal scan request
before association, so we should complete on last internal scan
command response.
