imsm: count arrays under VMD HBAs correctly
OROM defines maximum number of arrays supported. On array creation mdadm
checks if number of arrays doesn't exceed that limit, however it is not
calculated correctly for VMD now.
The current code performs a lookup of HBA using the id. VMD HBAs have
the same id so each lookup returns the same structure (first
encountered). Take a different approach for VMD HBAs. As id is not
unique and cannot be used for lookups, iterate over all VMD HBAs and
compare both id and HBA path.
