sched_ext: Fix exit_task leak on fork failure during enable
scx_fork() initializes tasks when scx_init_task_enabled is set, but
scx_cancel_fork() only exits them when scx_enabled() is true. A fork
that fails in the enable window (between releasing scx_fork_rwsem and
setting __scx_enabled) runs ops.init_task() but never ops.exit_task().
Gate scx_cancel_fork() on scx_init_task_enabled.
Fixes: 4269c603cc26 ("sched_ext: Enable scx_ops_init_task() separately")
