[media] vb2: don't set index, don't start streaming for write()
Two fixes:
- there is no need to set the index when calling dqbuf: dqbuf will
overwrite it.
- __vb2_init_fileio already starts streaming for write(), so there is
no need to do it again in __vb2_perform_fileio. It can never have
worked anyway: either __vb2_init_fileio succeeds in starting streaming
or it is never going to happen.
