fbdev: uvesafb: Call cn_del_callback() at the end of uvesafb_exit()

[ Upstream commit 1022e7e2f40574c74ed32c3811b03d26b0b81daf ]

Delete the v86d netlink only after all the VBE tasks have been
completed.

Fixes initial state restore on module unload:
uvesafb: VBE state restore call failed (eax=0x4f04, err=-19)
