Subject: [PATCH] media: venus: dec: Handle the case where find_format fails

Debugging the decoder on msm8916 I noticed the vdec probe was crashing if the fmt pointer was NULL.

A similar fix from Colin Ian King found by Coverity was implemented for the encoder. Implement the same fix on the decoder.
