Optimize memory usage in ngx_reset_pool

Description

In ngx_pool_t, the overhead of first block is sizeof(ngx_pool_t), the overhead of other blocks is sizeof(ngx_pool_data_t). But in function ngx_reset_pool, the last pointer always move to 'p + sizeof(ngx_pool_t)', and wastes some(small) memory.

I think we can optimize it, please see the patch, thanks.
