Define MAXCPU consistently between the kernel and KLDs.

Browse source 
This reverts r177661.  The change is no longer very useful since
out-of-tree KLDs will be built to target SMP kernels anyway.  Moveover
it breaks the KBI in !SMP builds since cpuset_t's layout depends on the
value of MAXCPU, and several kernel interfaces, notably
smp_rendezvous_cpus(), take a cpuset_t as a parameter.
