MIPS: reserve exception vector space ONLY ONCE

Browse source

[ Upstream commit abcabb9e30 ]

"cpu_probe" is called both by BP and APs, but reserving exception vector
(like 0x0-0x1000) called by "cpu_probe" need once and calling on APs is
too late since memblock is unavailable at that time.

So, reserve exception vector ONLY by BP.
