[PATCH] can: virtio: Fix comment in UAPI header

[Nathan Chancellor <nathan@kernel.org>]

When compile testing the UAPI headers with clang, there is an warning turned
error for using a C++ style ('//') comment, which is explicitly forbidden for
UAPI headers.

  In file included from <built-in>:1:
  ./usr/include/linux/virtio_can.h:29:35: error: // comments are not allowed in this language [-Werror,-Wcomment]
     29 | #define VIRTIO_CAN_MAX_DLEN    64 // this is like CANFD_MAX_DLEN
        |                                   ^
  1 error generated.

Switch to a standard C style comment.
