eventdev: restructure release function

Remove rte_event_dev_close() from rte_event_pmd_release() function so
that rte_event_pmd_release() can be used in stateless way. This will
enable rte_event_pmd_vdev_uninit() function to avoid using
eventdev_globals global variable and the need for exposing the a
global variable to PMD.
