staging: r8188eu: remove recv_osdep.h

The functions _rtw_init_recv_priv(), _rtw_free_recv_priv() and
rtw_recv_entry() are defined in rtw_recv.c. Move their prototypes from
recv_osdep.h to rtw_recv.h.

Move the last two remaining prototypes netdev_open() and netdev_close()
from recv_osdep.h to osdep_intf.h. That is a more appropriate place and
we can remove recv_osdep.h.
