i3c: mipi-i3c-hci: Fix missing xfer->completion in hci_cmd_v1_daa()

Due to missing completion object for the ENTDAA command transfer in the
hci_cmd_v1_daa() the wait_for_completion_timeout() will obviously
timeout even the transfer itself may succeed.

Fix this by setting the xfer->completion to the already initialized
completion object.
