Levi Yun d7ad05c86e timers/migration: Prevent out of bounds access on failure
When tmigr_setup_groups() fails the level 0 group allocation, then the
cleanup derefences index -1 of the local stack array.

Prevent this by checking the loop condition first.

Fixes: 7ee9887703 ("timers: Implement the hierarchical pull model")
