Subject: fuse: fix READDIRPLUS skipping an entry

From: Miklos Szeredi <[email protected]>

commit c6cdd51404b7ac12dd95173ddfc548c59ecf037f upstream.

Marios Titas running a Haskell program noticed a problem with fuse's
readdirplus: when it is interrupted by a signal, it skips one directory entry.

The reason is that fuse erronously updates ctx->pos after a failed dir_emit().

The issue originates from the patch adding readdirplus support.
