orangefs: saner arguments passing in readdir guts 

orangefs_dir_fill() doesn't use oi and dentry arguments at all
do_readdir() gets dentry, uses only dentry->d_inode; it also
gets oi, which is ORANGEFS_I(dentry->d_inode) (i.e. ->d_inode -
constant offset).
orangefs_dir_mode() gets dentry and oi, uses only to pass those
to do_readdir().
orangefs_dir_iterate() uses dentry and oi only to pass those to
orangefs_dir_fill() and orangefs_dir_more().

The only thing it really needs is ->d_inode; moreover, that's
better expressed as file_inode(file) - no need to go through
->f_path.dentry->d_inode.
