[ Upstream commit 63a41746827cb16dc6ad0d4d761ab4e7dda7a0c3 ]

When rmmod hip04_eth.ko, we can get the following warning:

Currently "rmmod hip04_eth.ko" call free_irq more than once
as devres_release_all and hip04_remove both call free_irq.
This results in a 'Trying to free already-free IRQ' warning.
To solve the problem free_irq has been moved out of hip04_remove.
