Currently after the hardware restart triggered from the driver, the
station interface connection remains intact, since a disconnect trigger
is not sent to userspace. This can lead to a problem in targets where
the wifi mac sequence is added by the firmware.

After the target restart, its wifi mac sequence number gets reset to
zero. Hence AP to which our device is connected will receive frames with
a  wifi mac sequence number jump to the past, thereby resulting in the
AP dropping all these frames, until the frame arrives with a wifi mac
sequence number which AP was expecting.

To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.

The other targets are not affected by this change, since the hardware
params flag is not set.
