From: Jack Morgenstein <ja...@dev.mellanox.co.il>
When running SRIOV, warnings for SRQ LIMIT events flood the Hypervisor's
message log when (correct, normally operating) apps use SRQ LIMIT events
as a trigger to post WQEs to SRQs.
Add more information to the existing debug printout for SRQ_LIMIT, and
output the warning messages only for the SRQ CATAS ERROR event.
Fixes: acba2420f9d2 ("mlx4_core: Add wrapper functions and comm channel and
slave event support to EQs")
Fixes: e0debf9cb50d ("mlx4_core: Reduce warning message for SRQ_LIMIT event to
debug level")
