torture: Don't leak shuffle_tmp_mask when shuffler kthread fails to start

Browse Source 
If torture_shuffle_init() successfully allocates shuffle_tmp_mask but
then fails to create the torture_shuffle kthread, the cpumask is never
freed.

Free the cpumask directly on the kthread-creation error path.
