fbdev: au1200fb: Fix a memory leak in au1200fb_drv_probe()

Browse Source 
[ Upstream commit ce4e25198a6aaaaf36248edf8daf3d744ec8e309 ]

In au1200fb_drv_probe(), when platform_get_irq fails(), it directly
returns from the function with an error code, which causes a memory
leak.

Replace it with a goto label to ensure proper cleanup.
