Subject: [PATCH 4/8] video: fbdev: au1200fb: Fix error handling path

'au1200fb_drv_probe()' can not fail after a succesful call to
'request_irq()'. So there is no point to call 'free_irq()' in the error
handling path.

Moreover, the hard coded AU1200_LCD_INT looks boggus since commit
1630d85a8312 ("au1200fb: fix hardcoded IRQ")

So, remove it.
