From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The call to sja1105_status_get to set various fields in the status
structure can potentially be skipped in a while-loop because of a couple
of prior continuation jump paths. This can potientially lead to checking
be checking against an uninitialized fields in the structure which may
lead to unexpected results. Fix this by ensuring all the fields in status
are initialized to zero to be safe.
Addresses-Coverity: ("Uninitialized scalar variable")
