4.19-stable review patch. If anyone has any objections, please let me know.

commit 2d861977e7314f00bf27d0db17c11ff5e85e609a upstream.
The loop at stb0899_search_carrier() starts with a random value for cfr, as reported by Coverity.
Initialize it to zero, just like stb0899_dvbs_algo() to ensure that carrier search won't bail out.
