[PATCH v1 12/22] xprtrdma: Eliminate "connstate" variable from rpcrdma_conn_upcall()

[Chuck Lever <chuck.lever@oracle.com>]

Clean up.

Since commit 173b8f49b3af ("xprtrdma: Demote "connect" log messages")
there has been no need to initialize connstat to zero. In fact, in
this code path there's now no reason not to set rep_connected
directly.
