entry: Fix compile error in dynamic_irqentry_exit_cond_resched()

kernel/entry/common.c: In function ‘dynamic_irqentry_exit_cond_resched’:
kernel/entry/common.c:409:14: error: implicit declaration of function ‘static_key_unlikely’; did you mean ‘static_key_enable’? [-Werror=implicit-function-declaration]
  409 |         if (!static_key_unlikely(&sk_dynamic_irqentry_exit_cond_resched))
      |              ^~~~~~~~~~~~~~~~~~~
      |              static_key_enable

static_key_unlikely() should be static_branch_unlikely().
