fuse: invalidate dentry on EEXIST creates or ENOENT deletes

Browse source

The EEXIST errors returned from server are strong sign that a local
negative dentry should be invalidated.  Similarly, The ENOENT errors from
server can also be a sign of revalidate failure.

This commit invalidates dentries on EEXIST creates and ENOENT deletes by
calling fuse_invalidate_entry(), which improves the consistency with no
performance degradation.
