Miklos Szeredi 91ec6c8559 Revert "fuse: in fuse_flush only wait if someone wants the return code" 
This reverts commit 5a8bee63b1.

Jürg Billeter reports the following regression:

  Since v6.3-rc1 commit 5a8bee63b1 ("fuse: in fuse_flush only wait if
  someone wants the return code") `fput()` is called asynchronously if a
  file is closed as part of a process exiting, i.e., if there was no
  explicit `close()` before exit.

  If the file was open for writing, also `put_write_access()` is called
  asynchronously as part of the async `fput()`.

  If that newly written file is an executable, attempting to `execve()` the
  new file can fail with `ETXTBSY` if it's called after the writer process
  exited but before the async `fput()` has run.
