These postfixes can be computed statically, and there is no need to
waste runtime resources.

A negative codec_id cannot be handled by the found_decoder API of
AVStream->info: if the codec_id is not recognized, found_decoder is set
to -codec_id, which has to be '<0' according to the API documentation.

This can cause NULL pointer dereferencing in try_decode_frame.

Also make sure the codec_type matches the expected one for codec_id.

Also correct the check to reject log < 7, because UPDATE_CACHE only
guarantees 25 meaningful bits.

This fixes undefined behavior:
runtime error: shift exponent is negative

Testing with START/STOP timers in get_ue_golomb, one for the first
branch (A) and one for the second (B), shows that there is practically no
slowdown, e.g. for the cavs decoder:

With the check in the B branch:
    629 decicycles in get_ue_golomb B, 4194260 runs,     44 skips
    433 decicycles in get_ue_golomb A,268434102 runs,   1354 skips

Without the check:
    624 decicycles in get_ue_golomb B, 4194273 runs,     31 skips
    433 decicycles in get_ue_golomb A,268434203 runs,   1253 skips

Since the B branch is executed far less often than the A branch, this
change is negligible, even more so for the h264 decoder, where the ratio
B/A is a lot smaller.
