Ignore failures when loading nf_conntrack_proto_sctp kernel module

Ignore failures if nf_conntrack_proto_sctp module failed to load.
Since RHEL 7.4, nf_conntrack_proto_sctp module is compiled into the
kernel instead of as a module as the sctp support.
TripleO will still try to load the module to support RHEL 7.3, but
in the future will remove the module management and rely on the kernel
provided in newer versions of RHEL.
