power: supply: rt9467: Prevent using uninitialized local variable in rt9467_set_value_from_ranges()
There is a typo in rt9467_set_value_from_ranges() that can cause leaving local
variable sel with an undefined value which is then used in regmap_field_write().
Found by Linux Verification Center (linuxtesting.org) with SVACE.
