The current driver will print all asynchronous events. Some of the
print levels are set improperly, e.g. SRQ limit reach and SRQ last
wqe reach, which may also occur during normal operation of the software.
Currently, the information of these event is printed as a warning,
which causes a large amount of printing even during normal use of the
application. As a result, the service performance deteriorates.
This patch fixes the printing storms by modifying the print level.
