[PATCH] tty: goldfish: Fix free_irq() on remove

[Vincent Whitchurch]

Pass the correct dev_id to free_irq() to fix this splat when the driver
is unbound:

 WARNING: CPU: 0 PID: 30 at kernel/irq/manage.c:1895 free_irq
 Trying to free already-free IRQ 65
 Call Trace:
  warn_slowpath_fmt
  free_irq
  goldfish_tty_remove
  platform_remove
  device_remove
  device_release_driver_internal
  device_driver_detach
  unbind_store
  drv_attr_store
  ...

Fixes: 465893e18878e119 ("tty: goldfish: support platform_device with id -1")
