kernel: fa-calibration: fix compilation error: 'fa undeclared'

In function 'fa_calib_gain_update()', the first argument ('fa') passed to 'from_timer()' is not declared anywhere, and thus the build throws compilation error. Fix this by declaring the variable and then defining it by the value produced by 'from_timer()'. Then we can use the same variable for the next steps.
