media: venus: dec: Handle the case where find_format fails
commit 06a2da340f762addc5935bf851d95b14d4692db2 upstream.
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.
