firmware: arm_scmi: Fix premature SCMI_XFER_FLAG_IS_RAW clearing in raw mode

The SCMI_XFER_FLAG_IS_RAW flag was being cleared prematurely in
scmi_xfer_raw_put() before the transfer completion was properly
acknowledged by the raw message handlers.

Move the clearing of SCMI_XFER_FLAG_IS_RAW and SCMI_XFER_FLAG_CHAN_SET
from scmi_xfer_raw_put() to __scmi_xfer_put() to ensure the flags remain
set throughout the entire raw message processing pipeline until the
transfer is returned to the free pool.
