powerpc/perf/hv-24x7: Update domain value check

Valid domain value is in range 1 to HV_PERF_DOMAIN_MAX. Current code has
check for domain value greater than or equal to HV_PERF_DOMAIN_MAX. But
the check for domain value 0 is missing.

Fix this issue by adding check for domain value 0.

Before:
  # ./perf stat -v -e hv_24x7/CPM_ADJUNCT_INST,domain=0,core=1/ sleep 1
  Using CPUID 00800200
  Control descriptor is not initialized
  Error:
  The sys_perf_event_open() syscall returned with 5 (Input/output error) for
  event (hv_24x7/CPM_ADJUNCT_INST,domain=0,core=1/).
  /bin/dmesg | grep -i perf may provide additional information.

  Result from dmesg:
  [   37.819387] hv-24x7: hcall failed: [0 0x60040000 0x100 0] => ret
  0xfffffffffffffffc (-4) detail=0x2000000 failing ix=0

After:
  # ./perf stat -v -e hv_24x7/CPM_ADJUNCT_INST,domain=0,core=1/ sleep 1
  Using CPUID 00800200
  Control descriptor is not initialized
  Warning:
  hv_24x7/CPM_ADJUNCT_INST,domain=0,core=1/ event is not supported by the kernel.
  failed to read counter hv_24x7/CPM_ADJUNCT_INST,domain=0,core=1/
