anv_state::offset in the context of anv_state_pool is equal to the offset from
the begining of block_pool + start_offset.
Like it is set in anv_state_pool_alloc_no_vg() in the path that allocs a new
block in anv_block_pool.
As anv_state_pool_return_chunk() expects only the offset from the begining of
anv_block_pool so here subtracting to make the path that grabs a larger chunk of
memory of the pool and split into smaler chunks to properly work.
