[PATCH v2 01/18] common/cnxk: fix engine capabilities fetch logic

[Rahul Bhansali]

From: Rakesh Kudurumalla <rkudurumalla at marvell.com>

For CN9k platform, incorrect status is checked from LOAD
FVC instruction while retrieving engine capabilities.

The loop is updated for a valid return status check on
LOADFVC instruction.
