qcacld-3.0: Make Stick time value to zero by default

Roaming to new AP is depends on the periodic scan which occurs every
10sec in fw. Due to the default value of sticky time (btm_sticky_time)
to BTM AP is 5 min, periodic roaming scan gets disabled in fw till
sticky timer expiry. So FW won’t trigger a periodic scan for 5 min,
in case of roaming to new AP by BTM.

In case if STA roams to new AP by BTM and Disassociation Timer
expires before Stick time, DUT is not able to roam to a candidate
AP till Stick time expiry.

In order to allow roaming just after disassociation timer expiry,
Make Stick time value to zero by default.
