Here's some more cleanups, mostly related to bSurpriseRemoved and
bDriverStopped.
Please apply them after the series I sent yesteday.
Changes in v2
- Fixed the header len calculation in patch 1. Thanks to Dan Carpenter
for spotting this mistake.

Define a struct ieee80211_qos_hdr in the validate_recv_data_frame
function. Use this struct to replace some numeric offsets and make the
code easier to understand.

There's no need to check bDriverStopped and bSurpriseRemoved in
issue_probereq_ex.
The code path looks like
issue_probereq_ex
_issue_probereq
dump_mgntframe
or
dump_mgntframe_and_wait_ack
All paths from dump_mgntframe check the two variables.
dump_mgntframe_and_wait_ack contains a check as well.

We can remove the checks for bDriverStopped and bSurpriseRemoved in
dump_mgntframe_and_wait_ack.
The code path from this function looks like
dump_mgntframe_and_wait_ack
rtl8188eu_mgnt_xmit
rtw_dump_xframe
loop over all fragments
rtw_write_port is called for each fragment. bSurpriseRemoved and
bDriverStopped are checked in rtw_write_port.
