media: venus: hfi_parser: add check to avoid out of bound access

Browse source

commit 172bf5a9ef upstream.

There is a possibility that init_codecs is invoked multiple times during
manipulated payload from video firmware. In such case, if codecs_count
can get incremented to value more than MAX_CODEC_NUM, there can be OOB
access. Reset the count so that it always starts from beginning.
