[PATCH v4 03/16] firmware: arm_scmi: Clean up channels on setup failure

[Sudeep Holla]

scmi_channels_setup() can fail after the common BASE channel or earlier
protocol channels have already been registered in the TX/RX IDRs.

Route this failure through the existing channel cleanup label so the
transport channels, transport devices and IDR state created before the
failure are released before the probe error path frees the SCMI instance
ID.

Fixes: 05a2801d8b90 ("firmware: arm_scmi: Use dedicated devices to initialize channels")
