mc: Fix manufacturer ID masking

Browse Source 
A potential future problem has been identified in the manufacturer
ID processing code for `mc info` command. Only 16 of 24 bits were
used. This is fixed now.

Also added support for ID 0x0FFFFF, the 'reserved' value as per
IPMI specification. It is now reported as 'Unspecified' unlike other
non-listed IDs that are still reported as 'Unknown'.

ID 0xFFFFFE is used for debugging purposes in hope that IANA won't
reach that number of entities any soon. If it will though, then
IANA's assignment will take precedence.
