fuse: break up fuse_open_common()
fuse_open_common() has a lot of code relevant only for regular files and
O_TRUNC in particular.
Copy the little bit of remaining code into fuse_dir_open() and stop using
this common helper for directory open.
Also split out fuse_dir_finish_open() from fuse_finish_open() before we add
inode io modes to fuse_finish_open().
