Zhang Changzhong 7ae6f2df43 can: proc: can_remove_proc(): silence remove_proc_entry warning ...

commit 3accbfdc36130282f5ae9e6eecfdf820169fedce upstream.

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.
