apr_pools: Set APR_POOL_DEBUG's pool->owner before using the pool.

The mutex synchronizing the pool in APR_POOL_DEBUG mode is created by
apr_pool_create_ex_debug() on the created pool itself but before initialising
the ->owner thread, so apr_thread_mutex_create() can abort() when reaching
apr_pool_check_owner() if APR_POOL_DEBUG_OWNER is set.

Move the ->owner initialisation before creating the ->mutex.
