[PATCH 1/3] x86/mce/AMD: Use msr_stat when clearing MCA_STATUS

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@xxxxxxx>

The value of MCA_STATUS is used as the MSR when clearing MCA_STATUS.

This may cause the following warning:
 unchecked MSR access error: WRMSR to 0x11b (tried to write 0x0000000000000000)
 Call Trace:
  <IRQ>
  ? amd_threshold_interrupt+0x209/0x220
  smp_threshold_interrupt+0x1b/0x40
  threshold_interrupt+0x89/0x90

Use msr_stat instead which has the MSR address.

Fixes: 37d43acfd79f ("x86/mce/AMD: Redo error logging from APIC LVT interrupt handlers")
