David Horstmann dcf73265ba Fix incorrect detection of HardwareModuleName ...

The hardware module name otherName SAN contains 2 OIDs:

 OtherName ::= SEQUENCE {
      type-id    OBJECT IDENTIFIER,
      value      [0] EXPLICIT ANY DEFINED BY type-id }

 HardwareModuleName ::= SEQUENCE {
                           hwType OBJECT IDENTIFIER,
                           hwSerialNum OCTET STRING }

The first, type-id, is the one that identifies the otherName as a
HardwareModuleName. The second, hwType, identifies the type of hardware.

This change fixes 2 issues:

1. We were erroneously trying to identify HardwareModuleNames by looking
at hwType, not type-id.
2. We accidentally inverted the check so that we were checking that
hwType did NOT match HardwareModuleName.

This fix ensures that type-id is correctly checked to make sure that it
matches the OID for HardwareModuleName.
