Oliver Hartkopp 9427584c2f can: isotp: check CAN address family in isotp_bind()

[ Upstream commit c6adf659a8ba85913e16a571d5a9bcd17d3d1234 ]

Add missing check to block non-AF_CAN binds.

Syzbot created some code which matched the right sockaddr struct size
but used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family
field:

bind$xdp(r2, &(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10)
                                ^^^^
This has no funtional impact but the userspace should be notified about
the wrong address family field content.
