net: sctp: Move sequence start handling into sctp_transport_get_idx()
net/sctp/proc.c: In function ‘sctp_transport_get_idx’: net/sctp/proc.c:313: warning: ‘obj’ may be used uninitialized in this function This is currently a false positive, as all callers check for a zero offset first, and handle this case in the exact same way. Move the check and handling into sctp_transport_get_idx() to kill the compiler warning, and avoid future bugs.
