Subject: [PATCH v3 2/5] mwifiex: Log an error on command failure during key-material upload

Sometimes the KEY_MATERIAL command can fail with the 88W8897 firmware
(when this happens exactly seems pretty random). This appears to prevent
the access point from starting, so it seems like a good idea to log an
error in that case.
