Revert "fs: fat: assign rootdir sector when accessing root directory"

This particular commit is causing a regression on stih410-b2260 and
other platforms when reading from FAT16.  Noting that I had rebased the
original fix from Thomas onto then-current master, there is also
question from Akashi-san if the change is still needed after other FAT
fixes that have gone in.

This reverts commit a68b0e11ea774492713a65d9fd5bb525fcaefff3.
