caif: Add missing braces to multiline if in cfctrl_linkup_request

[ Upstream commit 0c1db731bfcf3a9fd6c58132134f8b0f423552f0 ]

The indentation here implies this was meant to be a multi-line if.

Introduced several years back in commit c85c2951d4da1236e32f1858db418221e624aba5
("caif: Handle dev_queue_xmit errors.")
