[PATCH] xenpaging: don't try to log via xch if xc_interface_close fails

[Ian Campbell <ian.campbell@citrix.com>]

Since xch may not be valid (enough) any longer, xc_interface_close
already logs anything of any use before it tears down the integrated
logger so there is no need to log any further in the application via
that path.
