[Xen-devel] [PATCH -next] xen/pvcalls: remove set but not used variable 'intf'

[YueHaibing <yuehaibing@xxxxxxxxxx>]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/xen/pvcalls-back.c: In function 'pvcalls_sk_state_change':
drivers/xen/pvcalls-back.c:286:28: warning:
 variable 'intf' set but not used [-Wunused-but-set-variable]

It not used since e6587cdbd732 ("pvcalls-back: set -ENOTCONN in
pvcalls_conn_back_read")
