The error handling for platform_get_irq() failing no longer
works after a recent change, clang now points this out with
a warning:

drivers/gpu/host1x/dev.c:520:6: error: variable 'syncpt_irq' is uninitialized when used here [-Werror,-Wuninitialized]
        if (syncpt_irq < 0)
            ^~~~~~~~~~

Fix this by removing the variable and checking the correct
error status.
