 i2c: qcom-geni: release runtime PM reference when set_rate fails 
geni_i2c_xfer() takes a runtime-PM reference with pm_runtime_get_sync()
and then returns directly if the set_rate() callback fails, leaking the
reference and keeping the controller resumed for good. Route that error
through the existing cleanup path, which drops the reference and resets
the transfer state.

Found by code review; compile-tested with arm64 defconfig plus ACPI and
W=1.

Fixes: 10e74f4c50 ("i2c: qcom-geni: Enable I2C on SA8255p Qualcomm platforms")
