i2c: qcom-geni: release DMA channels on probe error
geni_i2c_init() grabs exclusive GPI tx/rx DMA channels when the serial
engine runs in GPI mode. If i2c_add_adapter() subsequently fails, probe
returns without releasing the channels, because the remove callback is
not invoked after a failed probe.
The adapter-registration failure path used to release the channels via
its err_dma label; that release was dropped when the probe tail was
restructured into geni_i2c_init().
Release the channels on the adapter-registration failure path, mirroring
geni_i2c_remove().
