fs/pipe: set FMODE_NOWAIT in create_pipe_files()

Browse Source 
Rather than have the caller set the FMODE_NOWAIT flags for both output
files, move it to create_pipe_files() where other f_mode flags are set
anyway with stream_open(). With that, both __do_pipe_flags() and
io_pipe() can remove the manual setting of the NOWAIT flags.

No intended functional changes, just a code cleanup.
