staging: rtl8723au: fix potential leak in update_bcn_wps_ie()
Fix a potential leak in the error path of function update_bcn_wps_ie(). Move the affected input verification to the beginning of the function so that it may return directly without leaking already allocated memory. Detected by Coverity - CID 1077718.
