fuse: fix uninitialized field in fuse_inode

I found problems accessing (executing) previously existing files, until
I did chmod on them (or setattr).

If the fi->attr_version is not initialized, then it could be
larger than fc->attr_version until a setattr is executed, and as a
result the inode attributes would never be set.
