From: Arumugam Kolappan <aru.kolappan@xxxxxxxxxx>
Presently, mlx5 driver dumps error CQE by default for few syndromes. Some
syndromes are expected due to application behavior[Ex: REMOTE_ACCESS_ERR
for revoking rkey before RDMA operation is completed]. There is no option
to disable the log if the application decided to do so. This patch
converts the log into dynamic print and by default, this debug print is
disabled. Users can enable/disable this logging at runtime if needed.
