Revert "NFSv4.2: Change the default KConfig value for READ_PLUS" 



This reverts commit 7fd461c4.

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.
