[PATCH V2 1/1] mwifiex: add tx info to skb when forming mgmt frame

[PATCH V2 1/1] mwifiex: add tx info to skb when forming mgmt frame

[Harvey Yang]

From: Huawei Yang <harvey.huawei.yang@gmail.com>

In function 'mwifiex_write_data_complete' it need tx info to find
the mwifiex_private to updates statistics and wake up tx queues.
Or we may trigger tx queues timeout when transmitting lots of mgmt
frames.

Here checkpatch.pl script reports whitespace damaged error.
I can fix it in my local tree and resend v3 to John after the 3.11 merge window.
