Subject: [PATCH][next] usbip: Fix incorrect double assignment to udc->ud.tcp_rx

From: Colin Ian King <colin.king@...onical.com>

Currently udc->ud.tcp_rx is being assigned twice, the second assignment
is incorrect, it should be to udc->ud.tcp_tx instead of rx. Fix this.

Addresses-Coverity: ("Unused value")
Fixes: 46613c9dfa96 ("usbip: fix vudc usbip_sockfd_store races leading to gpf")
