5f88049c0c rtlsdr_i2c_rad_reg: fix uninitialized variable 
This could lead to a misdetection of the tuner on some
platforms (E4K instead of FC0013 on the raspberry pi).

Thanks to Christoph Gommel for reporting this issue.

54fe3eca01 don't print i2c read/write errors for now 
During autodetection of the tuner they are
normal and may cause confusion.

f9b5d7b0a6 apply frequency correction value on the xtal clock directly 
by using this approach both, the tuning frequency and the sample rate
should be corrected at the same time.

589e96e8d8 Using a #define for constant 2^22 (not pow()) 
pow() might require the math library to be linked with
rtl-sdl (e.g. when compiling with clang), even though
it's actually constant.
