From: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx>
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.
Fixes: 8bd135bab91f ("V4L/DVB (9375): Add STB0899 support")
