[PATCH] opensm/osm_sa.{c,h}: osm_sa_db_file_dump() return values

[Yevgeny Kliteynik <kliteyn-LDSdmyG8hGV8YrgS2mwiifqBs+8SCbDb@public.gmane.org>]

Since osm_sa_db_file_dump() doesn't have to actually dump
SA DB, reflecting this in the function return values.

Function returns 0 if the SA DB was actually dumped,
>0 if there was no need to dump the SA DB and <0 if
some error occurred.
