If can_init_proc() fail to create /proc/net/can directory, can_remove_proc()
will trigger a warning:
WARNING: CPU: 6 PID: 7133 at fs/proc/generic.c:672 remove_proc_entry+0x17b0
Kernel panic - not syncing: panic_on_warn set ...
Fix to return early from can_remove_proc() if can proc_dir does not exists.
