[PATCH] eventdev/eth_tx: fix queue delete

[Naga Harish K S V <s.v.naga.harish.k@intel.com>]

Add spinlock protection in queue delete function.
This protects the data path while the queue delete operation
is in progress.

Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")
Cc: stable@dpdk.org
