atm: horizon: Fix irq release error

[ Upstream commit bde533f2ea607cbbbe76ef8738b36243939a7bc2 ]

atm_dev_register() can fail here and passed parameters to free irq
which is not initialised. Initialization of 'dev->irq' happened after
the 'goto out_free_irq'. So using 'irq' insted of 'dev->irq' in
free_irq().
