FruUtils: Add back the else in formatFRU.

There is no "else" in this if-statement and that causes the name very
wrong. The dbus path always be "/xyz/openbmc_project/FruDevice/UNKNOWN",
and the properties of the dbus-object are FRU_CUSTOM_FIELD_NAME which is
"INFO_AM".

Tested:
After applying this patch, information of all FRU becomes normal.
