[Xen-devel] [PATCH] tapaio build fix

[Samuel Thibault <samuel.thibault@xxxxxxxxxxxxx>]

With some combinations of compiler flags (no optimization, -Werror), the
compiler may complain that the function doesn't have a return statement
(even if the function actually just never returns), reported as bug
1128. This adds a dummy return statement.
