[Qemu-trivial] [PATCH] milkymist-minimac2: Use qemu_log_mask(GUEST_ERROR) instead of error_report

[Philippe Mathieu-Daudé]

qemu_log_mask(GUEST_ERROR) is more appropriate:

  $ qemu -d help
  Log items (comma separated):
  guest_errors    log when the guest OS does something invalid (eg accessing a 
non-existent register)
