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.
