Merge patch series "can: raw: optimize the sizes of struct uniqframe and struct raw_sock"

Vincent Mailhol <mailhol@kernel.org> says:

A few bytes can be shaved out of can raw's struct uniqframe and struct
raw_sock.

Patch #1 reorders struct uniqframe fields to save 8 bytes.

Patch #2 and #3 modify struct raw_sock to use bitfields and to reorder
its fields to save 24 bytes in total.
