Drew Galbraith 659f122c9e [Zion] Free memory that was allocated with the slab allocator. 
This reduces the number of active allocs by ~ 200.
Size 8: 142 -> 2
Size 16: 319 > 313
Size 32: 364-> 312

Drew Galbraith 6d27ee5dc5 [Zion] Add more debug information about kernel heap usage. 
This will be helpful as we work to improve it.

Without deallocations, we currently stand at the following alloc numbers
8 - 142
16 - 319
32 - 364

unsized - 305

total page usage including slabs is 12.
