wrc_main: set prev_state to 0 at compilation

By this when the link is down at startup, link_status is set to LINK_DOWN in wrc_check_link. It does not go through state LINK_WENT_DOWN. Due to this bug, despite of link was down one packet was sent by bootp. Signed-off-by: Adam Wujek <adam.wujek@cern.ch>
