Extend procfs status for bonded links to show "backup" and "inactive"flags

bond_info_show_slave in /drivers/net/bonding/bond_procfs.c currently does not show all the information that is relevant to determine whether a given slave is used for network traffic or not. In certain active-backup setups, this means one can not easily tell what's happening.

An example patch to fix this:

diff --git a/drivers/net/bonding/bond_procfs.c b/drivers/net/bonding/bond_procfs.c
index 3cea38d..48ac2a4 100644
--- a/drivers/net/bonding/bond_procfs.c
