[Tux3] Userspace - Removing inode on file delete

[kushal dalmia]

Resending the patch without wrapping -

Just added the purge_inum() call in tux3.c and tux3fuse.c to remove the
inode entry of the deleted file from the ileaf.
Also added a sync_super() in tux3_unlink() of tux3fuse.c. The patch file is
attached herewith.
