[PATCH v8 37/44] kernel-shark: Redefine the args of KsPlot::getColor()

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

The function was originally designed to return the color that
correspond to a given PID. However we now have 3 different color
maps (for PID, CPU Id and Stream Id) and the same method can be
used with each of the 3 maps. We also want to prevent the method
from modifying the map itself.
