[PATCH] i2c: qcom-geni: Fix return value for master_xfer

[jorcrous]

From: Jordan Crouse <jorcrous@xxxxxxxxxx>

The master_xfer function is supposed to return the number of messages that
were processed. Both  geni_i2c_gpi_xfer and geni_i2c_fifo_xfer are
returning 0 which is being interpeted as a error in the upper layers.

Fixes: 8133682618cb ("i2c: qcom-geni: Add support for GPI DMA")
