fbdev: arcfb: Fix error handling in arcfb_probe()

[ Upstream commit 5a6bef734247c7a8c19511664ff77634ab86f45b ]

Smatch complains that:
arcfb_probe() warn: 'irq' from request_irq() not released on lines: 587.

Fix error handling in the arcfb_probe() function. If IO addresses are
not provided or framebuffer registration fails, the code will jump to
the err_addr or err_register_fb label to release resources.
If IRQ request fails, previously allocated resources will be freed.
