Zhang Shurong 50e4b32d2e fbdev: au1200fb: Fix missing IRQ check in au1200fb_drv_probe

[ Upstream commit 4e88761f5f ]

This func misses checking for platform_get_irq()'s call and may passes the
negative error codes to request_irq(), which takes unsigned IRQ #,
causing it to fail with -EINVAL, overriding an original error code.

Fix this by stop calling request_irq() with invalid IRQ #s.
