qcacld-3.0: Reset memory allocation of BSS description

qcacld-2.0 to qcacld-3.0 propagation

In CCX, BSS description is sent as part of beacon report. If BSS
description has random values, it leads to CCX certification failure.
Fix this by resetting memory allocated with zero. Also, reset memory
allocated to send beacon report to avoid this issue.
