[PATCH 6.6 160/396] cifs: make cifs_chan_update_iface() a void function

From: Dan Carpenter <dan.carpenter@linaro.org>

[ Upstream commit 8d606c311b75e81063b4ea650b301cbe0c4ed5e1 ]

The return values for cifs_chan_update_iface() didn't match what the
documentation said and nothing was checking them anyway. Just make it
a void function.
