Revert "NFSv4.2: Change the default KConfig value for READ_PLUS"
This reverts commit 7fd461c47c6cfab4ca4d003790ec276209e52978.
Unfortunately, it has come to our attention that there is still a bug
somewhere in the READ_PLUS code that can result in nfsroot systems on
ARM to crash during boot.
Let's do the right thing and revert this change so we don't break
people's nfsroot setups.
