fuse: fix READDIRPLUS skipping an entry
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.
