media: coda: ctx->codec is not NULL in coda_alloc_framebuffers
This fixes a smatch warning: drivers/media/platform/coda/coda-bit.c:415 coda_alloc_framebuffers() error: we previously assumed 'ctx->codec' could be null (see line 396) coda_alloc_framebuffers() is called from coda_start_encoding() and __coda_start_decoding(). Both dereference ctx->codec before calling coda_alloc_framebuffers() in lines 935 and 1649, so ctx->codec can not be NULL.
