libmemtrack: Fix integer overflow in kgsl function

In the kgsl function which gets memory info for a
pid, there could be possibility of integer overflow
in operations with size, mapsize, accounted_size,
and unaccounted_size due to which result might be
smaller than these values. External inputs size and
mapsize are verified, and overflow check has been added.
