[PATCH v2 07/28] common/cnxk: fix issues in soft expiry disable path

[Nithin Dabilpuram]

Fix issues in mode where soft expiry is disabled in RoC.
When soft expiry support is not enabled in inline device,
memory is not allocated for the ring base array and should
not be accessed.

Fixes: bea5d990a93b ("net/cnxk: support outbound soft expiry notification")
