[V3 06/10] powerpc, perf: Change the name of HW PMU branch filter tracking variable

[Anshuman Khandual <khandual@linux.vnet.ibm.com>]

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.
