avcodec/smvjpegdec: Make decoder init-threadsafe

The only thing that stands in the way of adding the
FF_CODEC_CAP_INIT_THREADSAFE flag to the SMV JPEG decoder is its usage
of ff_codec_open2_recursive(): This function requires its caller to hold
the lock for the mutex that guards initialization of AVCodecContexts
whose codecs have a non-threadsafe init function and only callers whose
codec does not have the FF_CODEC_CAP_INIT_THREADSAFE flag set hold said
lock (the others don't need to care about said lock). But one can set
the flag if one switches to avcodec_open2() at the same time.
