wlan: use irq API's to acquire spin lock

data_queue_lock is called in interrupt context and thread context,
there can be a spinlock recursion if thread context acquires lock
first and then interrupt context tries to acquire lock.

To address this use irq API's spin_lock_irq() and spin_unlock_irq().
