qcacmn: Prevent rate stats from printing in kmsg

Browse Source 
Do not print rate statistics on the console or kernel logs. Excessive
logging in kernel messages can lead to kernel panic.

Change DP_PRINT_STATS to not print in kernel logs.

Note that this is an interim solution. Ideally these prints from DP
module should be QDF_TRACE_LEVEL_DEBUG and logged to QXDM. Currently
DEBUG trace level is disabled for DP module.
