Subject: [PATCH] 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.
