Subject: [PATCH net-next v4] net: can: Fix compiling warnings for two functions

There are two warnings 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")

 v1->v2: change patch description typo error, 'warings' to 'warnings'.
 v2->v3: change subject of patch.
 v3->v4: change the alignment of two functions.
