Subject: [PATCH] i2c: qcom-geni: Use dev_err_probe() for GPI DMA error

The GPI DMA engine driver can be compiled as a module, in which case the
likely probe deferral "error" shows up in the kernel log. Switch to
using dev_err_probe() to silence this warning and to ensure that
"devices_deferred" in debugfs carries this information.
