sched/task: fix gettid by moving tls_dup_info after child pid initialization

Browse Source 
Move tls_dup_info() call to after child process priority is set, ensuring
the child's pid is properly initialized before duplicating TLS information.
This fixes incorrect thread ID assignment during task fork operations.
