Seemp: Logging each Kernel Protect Report only once 



KP Report which was sent to Linux from QHEE KP will be processed
by kernel and details of report will be logged into ring buffer.
However each report should be logged once and if the report is
already logged we can skip it from logging again. Also actor name
field of KP report is getting logged now.
