[ofa-general] opensm master determination

[Nicolas Morey Chaisemartin]

For the same priority level,  the lowest GUID take control:
in osm_sminfo_rcv.c:

/**********************************************************************
 Return TRUE if the remote sm given (by ib_sm_info_t) is higher,
 return FALSE otherwise.
 By higher - we mean: SM with higher priority or with same priority
 and lower GUID.
**********************************************************************/
static inline boolean_t
__osm_sminfo_rcv_remote_sm_is_higher(IN osm_sm_t * sm,
                                     IN const ib_sm_info_t * p_remote_smi)
