linuxmodule: fix another HandlerStrings issue

In the new alloc_handler_string() code, we no longer have access to Handler*
so the caller is responsible to setting HandlerString::flags.
Unfortunately, this member is a sentinel that indicates whether the HS is in
use or not since in-use and not-in-use HSs exist in the same List.  Since it
is the callers responsibility to set flags to an actual value,
alloca_handler_string need only set flags to any value other than 0 so that
two callers do not get the same HandlerString.
