Merge branch 'wireless'

John W. Linville says:

====================
This is a batch of fixes intended for the 3.9 stream...

Avinash Patil gives us a mwifiex fix to prevent a system freeze when
that driver is unloaded.

Daniel Drake brings a patch to avoid dropping the carrier flag across a
suspend.  This prevents improper packet drops.

Wei Yongjun delivers a brcmfmac for a lock leak on an error path.
