[PATCH -next v2] scsi: mpi3mr: Make some symbols static

[Yang Yingliang <yangyingliang@huawei.com>]

Fix the following warnings:

  drivers/scsi/mpi3mr/mpi3mr_os.c:24:5: warning: symbol 'prot_mask' was not declared. Should it be static?
  drivers/scsi/mpi3mr/mpi3mr_os.c:28:5: warning: symbol 'prot_guard_mask' was not declared. Should it be static?
  drivers/scsi/mpi3mr/mpi3mr_os.c:31:5: warning: symbol 'logging_level' was not declared. Should it be static?
