Subject: [PATCH] hwmon: (aquacomputer_d5next) Fix incorrect PWM value readout

Commit 662d20b3a5af ("hwmon: (aquacomputer_d5next) Add support for
temperature sensor offsets") changed aqc_get_ctrl_val() to return
the value through a parameter instead of through the return value,
but didn't fix up a case that relied on the old behavior. Fix it
to use the proper received value and not the return code.
