There are two warings in net/can, fix them by setting bcm_sock_no_ioctlcmd
and raw_sock_no_ioctlcmd as static.

net/can/bcm.c:1683:5: warning: symbol 'bcm_sock_no_ioctlcmd' was not declared. Should it be static?
net/can/raw.c:840:5: warning: symbol 'raw_sock_no_ioctlcmd' was not declared. Should it be static?

Fixes: 473d924d7d46 ("can: fix ioctl function removal")

Thanks Mao!

Btw. what kind of compiler/make switches are you using so that I can see these warnings myself the next time?

Best regards,
Oliver
