fs/9p: Revert "fs/9p: fix dups even in uncached mode"
This reverts commit be57855f505003c5cafff40338d5d0f23b00ba4d.
It caused a regression involving duplicate inode numbers in
some tester trees. The bad behavior seems to be dependent on inode
reuse policy in underlying file system, so it did not trigger in my
test setup.
