Currently, on obss color collision detection driver sends bss color
change IE in beacon and updates the color switch count in IE in
every beacon until color switch count reaches 0.
If the wlan driver enters suspend during this updation of bss color
change IE in beacon, the bss color change is not completed until wlan
resumes. This will lead to delay in bss color change after bss color
collision is detected.
To fix this issue, acquire wakelock once obss color collision is
detected and release it once obss color change is completed. This fix
is similar to how CSA is handled currently in driver.
