soc: qcom: pbs: fix device leak on lookup

commit 94124bf253d24b13e89c45618a168d5a1d8a61e7 upstream.

Make sure to drop the reference taken to the pbs platform device when
looking up its driver data.

Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.
