sctp: unify sctp_make_op_error_fixed and sctp_make_op_error_space

These two variants are very close to each other and can be merged to avoid code duplication. That's what this patchset does.

First, we allow sctp_init_cause to return errors, which then allow us to add sctp_make_op_error_limited that handles both situations.

sctp: allow sctp_init_cause to return errors
sctp: add sctp_make_op_error_limited and reuse inner functions
