fbdev: make unregister/unlink functions not fail
Except for driver bugs (which we'll catch with a WARN_ON) this is only
to report failures of the new driver taking over the console. There's
nothing the outgoing driver can do about that, and no one ever
bothered to actually look at these return values. So remove them all.
v2: fixup unregister_framebuffer in savagefb, fbtft, ivtvfb, and neofb
drivers, reported by kbuild.
