common/ompio: fix an ordering problem during file_open

the sharedfp component has to be selected and opened before
we set the default file view during file_open. Otherwise
there is a sperious error message from the sharefp_file_seek
operation that is called during the file_set_view.

Fixes Issue open-mpi#5560
