Subject: [V6 07/11] powerpc, perf: Change the name of HW PMU branch filter tracking variable

This patch simply changes the name of the variable from 'bhrb_filter' to
'bhrb_hw_filter' in order to add one more variable which will track SW
filters in generic powerpc book3s code which will be implemented in the
subsequent patch. This patch does not change any functionality.
