[PATCH v7 6/8] mpt3sas: Don't modify EEDPTagMode field setting on SAS3.5 HBA devices

[Suganath Prabu]

If EEDPTagMode field in manufacturing page11 is set then
unset it. This is needed to fix a hardware bug only
in SAS3/SAS2 cards. So, skipping EEDPTagMode changes
in Manufacturing page11 for SAS 3.5 controllers.
