When removing a device, the fail-safe checks that it is not within its
datapath before cleaning it.
When checking whether an Rx burst should be performed on a device, the
remove flag is not checked. Thus the port could still enter its datapath
and miss a removal round. Furthermore, there is a race between the
thread removing the device and the polling thread.
Check the remove flag before entering a sub-device Rx burst when in safe
mode. This check mitigates the aforementioned race condition.

With the current scheme of event queue configuration the cfg schedule
type macros (RTE_EVENT_QUEUE_CFG_*_ONLY) are inconsistent with the
event schedule type (RTE_SCHED_TYPE_*) this requires unnecessary
conversion between the fastpath and slowpath API's while scheduling
events or configuring event queues.
This patch aims to fix such inconsistency by using event schedule
types (RTE_SCHED_TYPE_*) for event queue configuration.
This patch also fixes example/eventdev_pipeline_sw_pmd as it doesn't
convert RTE_EVENT_QUEUE_CFG_*_ONLY to RTE_SCHED_TYPE_* which leads to
improper events being enqueued to the eventdev.
