[PATCH] rsi_91x_mac80211: fix structurally dead code

From: Gustavo A. R. Silva
Date: Thu Apr 26 2018 - 09:01:50 EST


Function rsi_hal_key_config returns before reaching code at line
922 if (status), hence this code is structurally dead.

Fix this by storing the value returned by rsi_hal_load_key
into _status_ for its further evaluation and use.
