hwmon: qpnp-adc-current: Fix external rsense value 



When external rsense is selected the api used to
calculate the rsense needs to return back. Instead
it recalculates the rsense using the trim procedure
used for calcuating the internal rsense. Fix it
by returning the value that is used for the external
rsense.
