[dpdk-stable] [PATCH 20.11 2/3] event/octeontx2: configure crypto adapter xaq pool

[Shijith Thotton]

[ upstream commit 849111aec74dd3282a70b540683fcdc86be155d8 ]

Configure xaq pool based on number of in-use crypto queues to avoid CPT
add work failure due to xaq buffer run out. This patch configures
OTX2_CPT_DEFAULT_CMD_QLEN number of xae entries per queue pair.

Fixes: 29768f78d5a7 ("event/octeontx2: add crypto adapter framework")
