net: sctp: Inline the functions from command.c
sctp_init_cmd_seq() and sctp_next_cmd() are only called from one place. The call sequence for sctp_add_cmd_sf() is likely to be longer than the inlined code. With sctp_add_cmd_sf() inlined the compiler can optimise repeated calls. Signed-off-by: David Laight <david.laight@aculab.com> Signed-off-by: David S. Miller <davem@davemloft.net>
