regmap-irq: Fix dereference of a potentially null d->virt_buf
The clean up of struct d can potentiallly index into a null array d->virt_buf causing errorenous pointer dereferencing issues on kfree calls. Fix this by adding a null check on d->virt_buf before attempting to traverse the array to kfree the objects.
