net/mlx4_core: Eliminate warning messages for SRQ_LIMIT under SRIOV

[ Upstream commit 9577b174 ]

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: acba2420 ("mlx4_core: Add wrapper functions and comm channel and slave event support to EQs")
Fixes: e0debf9c ("mlx4_core: Reduce warning message for SRQ_LIMIT event to debug level")
