hv:unify spin_lock initialization

Browse Source 
will follow this convention for spin lock initialization:
-- for simple global variable locks, use this style:
   static spinlock_t xxx_spinlock = {.head = 0U, .tail = 0U,}
-- for the locks inside a data structure, need to call
   spinlock_init to initialize.
