When an allocator is created with a base of 0 the first allocated block could well be 0. This appears to be an error since gk20a_balloc() normally returns 0 for error cases. This patch removes one block from the allocatable resources when base is set to 0 so that code using gk20a_balloc() does not get tricked into thinking valid allocations are OOM cases.
