osd: use CEPH_FEATUREMASK_CRUSH_MSR, not CEPH_FEATURE_CRUSH_MSR

osd: use CEPH_FEATUREMASK_CRUSH_MSR, not CEPH_FEATURE_CRUSH_MSR

This was simply a mistake:

uint64_t features = 0;
features |= CEPH_FEATURE_CRUSH_MSR;
ceph_assert(HAVE_FEATURE(features, CRUSH_MSR));

will fail the assert as CEPH_FEATURE_CRUSH_MSR lacks the mask.  In
basically all cases, CEPH_FEATUREMASK_* is the correct choice.
