[PATCH 5.18 0502/1095] i2c: qcom-geni: Use the correct return value

[Greg Kroah-Hartman]

From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>

[ Upstream commit b3f0ceb7c2037c6e3affd7d9c84ac5f97af7a5b5 ]

The introduction of GPI support moved things around and instead of
returning the result from geni_i2c_xfer() the number of messages in the
request was returned, ignoring the actual result. Fix this.

Fixes: d8703554f4de ("i2c: qcom-geni: Add support for GPI DMA")
