gpu: nvgpu: Handle allocators with a base of 0
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.
