Remove dependencies on two non-exported functions (si_swapinfo() and
vmalloc_nr_pages()) along with one non-existant one. User space
clients of the sysstats driver will need to obtain swap_total from
/proc/meminfo's SwapTotal, swap_used from SwapTotal - SwapFree, and
vmalloc_total from VmallocUsed.
For now, the unreclaimable field will now return 0 as a value or just
the KGSL allocated memory, depending on the call path.
