Instead of repeatedly bombarding the user with a request to reboot and
increase the stolen size with every fb refresh, just inform them the
first time only.
v2: Rearrange code so the hint to increase the amount of memory stolen
by the BIOS is only emitted if we fail to find sufficient stolen memory
for FBC.
