[dpdk-dev] [PATCH] eventdev: fix device probe and remove for secondary process

[pbhagavatula at marvell.com]

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

When probing event device in secondary process skip reinitializing
the device data structure as it is already done in primary process.

When removing event device in secondary process skip closing the
event device as it should be done by primary process.

Fixes: 322d0345c2bc ("eventdev: implement PMD registration functions")
