[PATCH] cpuset: remove useless local variable initialization

Remove a useless variable initialization in cpuset __cpuset_zone_allowed().
 The local variable 'allowed' is unconditionally set before use, later on
in the code, so does not need to be initialized.

Not that it seems to matter to the code generated any, as the compiler
optimizes out the superfluous assignment anyway.
