qcacmn: Add support to acquire wake lock during user scan

Browse Source 
Acquire wakelock to handle the case where APP's send
scan to connect. If suspend is received during scan, scan will be
aborted and APP will not get scan result and will not connect.
eg if PNO is implemented in framework.

Fix is to avoid the system suspend by taking the wake-lock
during scan. Added INI wake_lock_in_user_scan to control this.
The INI is disabled by default.
