Work by Jeffry Molanus.

When we issue the MODE SENSE(10) we should prior to that set the page control field to 1, and verify the setting is changeable before we just blindly modify the bit. the STEC zeusram does not support changing this bit and as result we generate sense data which triggers the ereport over and over and over again as we dont learn from our failures.

Use STEC ZeusRAM or other devices that don't support changing the WCE bit.

Tested also on:
pvscsi drives - don't support the Page Control "changeable".
seagate drives behind mpt_sas - support the Page Control "changeable" and report it as 1.
