md_clear is misspelt
In #10953, we integrated support for mitigations for the microarchitectural data sampling vulnerabilities found by Intel. Part of this new support includes enumeration of the MD_CLEAR CPU feature. Unfortunately it seems we've misspelt the feature name as
mb_clear in a couple of places.

To test this I ran a wsdiff against the system. Notably there were two entries that weren't due to the normal DOF/timestamp problem:
platform/i86xpv/kernel/amd64/unix NOTE: ELF .rodata difference detected. 16672,16673c16672,16673 < 0650440 m b _ c l e a r \0 c o r e _ t h < 635f626d 7261656c 726f6300 68745f65 --- > 0650440 m d _ c l e a r \0 c o r e _ t h > 635f646d 7261656c 726f6300 68745f65 platform/i86pc/kernel/amd64/unix NOTE: ELF .rodata difference detected. 16969,16970c16969,16970 < 0654040 m b _ c l e a r \0 c o r e _ t h < 635f626d 7261656c 726f6300 68745f65 --- > 0654040 m d _ c l e a r \0 c o r e _ t h > 635f646d 7261656c 726f6300 68745f65
In this case, this is exactly what we expected! wsdiff confirmed that the only change in unix was the spelling.
