tty: goldfish: Fix free_irq() on remove
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
