qcacld-3.0: Fix Integer overflow while sending beacon report

sme_ese_send_beacon_req_scan_results sends number of bss description
present in beacon report through bcn_report->numBss. For each
iteration driver could send max 4 BSS. In case if driver has to send
beacon report for more than 4 BSS, It sends 4 BSS per iteration. Once
first four results are sent and bcn_report->numBss is not set to 0,
in next iteration bcn_report->numBss++ start from 4 instead of 0.
This Result in sending value more than 4 instead of 4 for next rest
BSS and leads to Integer overflow for bcn_report->numBss.

Driver should memset beacon_rep buffer for each iteration in order to
prevent Integer overflow of bcn_report->numBss. By this driver
could send fresh beacon report (independent of previous beacon report)
in each iteration.

Fix is to memset beacon_rep buffer to zero after sending beacon
report in each iteration in sme_ese_send_beacon_req_scan_results.
