[PATCH net-next] net: sctp: minor: remove dead code from sctp_packet

[Daniel Borkmann <dborkman@redhat.com>]

struct sctp_packet is currently embedded into sctp_transport or
sits on the stack as 'singleton' in sctp_outq_flush(). Therefore,
its member 'malloced' is always 0, thus a kfree() is never called.
Because of that, we can just remove this code.

 That is finally the last one of all these cases to get rid of
 'malloced' structure members.
