usb: host: ohci-exynos: Fix error handling in exynos_ohci_probe()

Browse Source 
If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ohci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.
