Stop setting CONFIG_MAXSMP and adjust NR_CPUS
    
    During the Kconfig factor, CONFIG_MAXSMP was set for all builds instead
    of just debug builds. This bumps the NR_CPUs up to 8192 which is far
    more than anyone actually needs for Fedora. Stop setting CONFIG_MAXSMP
    on non-debug configs and adjust NR_CPUs back to what it was before.
