Subject: [PATCH] [media] c8sectpfe: Fix uninitialized return in load_c8sectpfe_fw_step1()

In case of failure loading the firmware, function
load_c8sectpfe_fw_step1() uses the uninitialized variable ret as return
value instead of the retrieved error value. Make sure the result is
deterministic. Detected by Coverity CID 1324230.

Compile tested only. Applies against linux-next.
