usb: host: ehci-exynos: Fix error check in exynos_ehci_probe()
commit 44ed240d62736ad29943ec01e41e194b96f7c5e9 upstream.
If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ehci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.
Fixes: 1bcc5aa87f04 ("USB: Add initial S5P EHCI driver")
