* If EEDPTagMode field in manufacturing page11 is set,
unset it. This is needed to fix a hardware bug
in SAS3/SAS2 cards, So, skipping EEDPTagMode changes
in Manufacturing page11 for SAS35 controllers.
* Fix driver modifying NVRAM/persistent data in
Manufacturing page11 along with current copy. Driver should
change only current copy of Manufacturing page11
