gpu: host1x: fix uninitialized variable use

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.
