From: Pavan Bhagavatula <pbhagavatula at caviumnetworks.com>
Add schedule type queue attribute so that it can be queried along with
the queue config structure.
Signed-off-by: Pavan Nikhilesh <pbhagavatula at caviumnetworks.com>

v2 changes:
- return EOVERFLOW when schedule_type is requested and event_queue_cfg is set
to *ALL_TYPES*.
