platform/x86: int3472: Don't leak reference on error

The for_each_acpi_consumer_dev() takes a reference to the iterator
and if we break a loop we must drop that reference. This usually
happens when error handling is involved. However it's not the case
for skl_int3472_fill_clk_pdata().

Don't leak reference on error by dropping it properly.
