drm/gma500: Fix call trace when psb_gem_mm_init() fails

drm/gma500: Fix call trace when psb_gem_mm_init() fails

[ Upstream commit da596080b2b400c50fe9f8f237bcaf09fed06af8 ]

Because the gma_irq_install() is call after psb_gem_mm_init() function,
when psb_gem_mm_init() fails, the interrupt line haven't been allocated.
Yet the gma_irq_uninstall() is called in the psb_driver_unload() function
without checking if checking the irq is registered or not.

The calltrace is appended as following:
