Subject: [patch] caif: remove unneeded null check in caif_connect()

From: Dan Carpenter <[email-masked]>

We already dereferenced uaddr towards the start of the function when we
checked that "uaddr->sa_family != AF_CAIF".  Both the check here and the
earlier check were added in bece7b2398d0: "caif: Rewritten socket
implementation".  Before that patch, we assumed that we recieved a valid
pointer for uaddr, and based on that, I have removed this check.
