avcodec/h264_cavlc: Remove redundant check 

The only caller to ff_h264_decode_init_vlc() already uses
ff_thread_once() for the call; ergo the check via a simple int with
static storage duration in ff_h264_decode_init_vlc() is redundant.
And if it were not redundant, it would be a potential for data races.
So remove it.
