net: ipa: set error code in gsi_channel_setup()

[ Upstream commit 1d23a56b0296d29e7047b41fe0a42a001036160d ]

In gsi_channel_setup(), we check to see if the configuration data
contains any information about channels that are not supported by
the hardware.  If one is found, we abort the setup process, but
the error code (ret) is not set in this case.  Fix this bug.
