Correct return code of e4k_reg_write().
...
In contradiction with the documentation, e4k_reg_write() was
returning the value 2 upon success (the number of bytes written),
not zero as documented.
Patched to return zero upon success.
As a consequence, this corrects also the return value of
e4k_reg_set_mask() and e4k_dc_offset_calibrate().

lib: enable standby mode of e4k and r820t on exit
...
Since the R820T is a power hog and gets quite hot,
this makes sense, especially when being battery-
powered.
