#2 Xattr Fix

[Ben Banfield-Zanin]

Fixes requests to any of the xattr functions returning the wrong error code and generating spurious error messages when using a FUSE filesystem. ENOTSUPP which was the return code is for NFS mainly and not the standard not support error code. ENOSYS is the standard and matches what the C FUSE library does.

Goes beyond the xattr fix in Anurag Sharma's patch, which pointed me in the right direction, as it also fixes the case where Filesystem3 is implemented directly and not just from an adaptor.

Hope this helps
