f2fs: doc: Fix bouncing email address for Sahitya Tummala

The servers for the @codeaurora domain are long retired and any messages
addressed there will bounce.  Sahitya Tummala has a .mailmap entry to an
updated address, but the documentation files still list @codeaurora
which might be a problem for anyone reading the documentation directly.
Update the documentation files to match the .mailmap update.
