can: dev: prevent potential information leak in can_fill_info()
[ Upstream commit b552766c872f5b0d90323b24e4c9e8fa67486dd5 ]
The "bec" struct isn't necessarily always initialized. For example, the
mcp251xfd_get_berr_counter() function doesn't initialize anything if the
interface is down.
Fixes: 52c793f24054 ("can: netlink support for bus-error reporting and counters")
