tools/mm: fix slabinfo crash when MAX_SLABS is exceeded
The number of slabs can easily exceed the hard coded MAX_SLABS in the
slabinfo tool, causing it to overwrite memory and crash.
Increase the value of MAX_SLABS, and check if that has been exceeded for
each new slab, instead of at the end when it's already too late. Also
move the check for MAX_ALIASES into the loop body.
