iio: temperature: ltc2983: Fix n_wires default bypassing rotation check

When adi,number-of-wires is absent, n_wires is left at 0. The binding
documents a default of 2 wires, matching the hardware default. However
the current-rotate validation checks n_wires == 2 || n_wires == 3, so
with n_wires = 0 the guard is bypassed and adi,current-rotate is accepted
for a 2-wire RTD.

Initialize n_wires = 2 to match the binding default and ensure the
rotation check fires correctly when the property is absent.
