usb: musb: Fix trying to free already-free IRQ 4
When unloading omap2430, we can get the following splat:
WARNING: CPU: 1 PID: 295 at kernel/irq/manage.c:1478 __free_irq+0xa8/0x2c8
Trying to free already-free IRQ 4
...
[<c01a8b78>] (free_irq) from [<bf0aea84>]
(musbhs_dma_controller_destroy+0x28/0xb0 [musb_hdrc])
[<bf0aea84>] (musbhs_dma_controller_destroy [musb_hdrc]) from
[<bf09f88c>] (musb_remove+0xf0/0x12c [musb_hdrc])
[<bf09f88c>] (musb_remove [musb_hdrc]) from [<c056a384>]
(platform_drv_remove+0x24/0x3c)
...
This is because the irq number in use is 260 nowadays, and the dma
controller is using u8 instead of int.
