[PATCH] warning in SCTP

[Meelis Roos <mroos@linux.ee>]

   CC [M]  net/sctp/sm_make_chunk.o
net/sctp/sm_make_chunk.c: In function 'sctp_unpack_cookie':
net/sctp/sm_make_chunk.c:1358: warning: initialization discards qualifiers from pointer target type

The reason is that sctp_unpack_cookie() takes a const struct 
sctp_endpoint and modifies the digest in it (digest being embedded in 
the struct, not a pointer). So sctp_unpack_cookie really does not use 
the argument as const, mark it as such.
