Zongjie Li 5a08a72da3 fbdev: arcfb: Fix error handling in arcfb_probe()

[ Upstream commit 5a6bef7342 ]

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.

Fixes: 1154ea7dcd ("[PATCH] Framebuffer driver for Arc LCD board")
