x86/oprofile: Modify initialization of num_virt_counters
Models that do not yet support counter multiplexing have to setup num_virt_counters. This patch implements the setup from num_counters if num_virt_counters is not set. Thus, num_virt_counters must be setup only for multiplexing support. Signed-off-by: Robert Richter <robert.richter@amd.com>
