MINOR: compression: always create the compression pool

Surprisingly, the compression pool was created at runtime on first use,
which is not very convenient, has performance and reliability impacts,
and even makes monitoring less easy. Let's move the pool creation at
startup time instead. This even removes the need for the spinlock in
case USE_ZLIB is not defined.
