bonding module ignores resend_igmp parameter

[Piotr Meyer]

Bonding module v3.7.0 (kernel 2.6.38.x) has been modified to send IGMP joins not only in round-robin mode, as was in 2.6.36, see:

but also in primary-backup.

Unfortunately, check for resend_igmp was missed until 3.0:

Current (2.6.38.7) code leads to continuous igmp flood, regardless of resend_igmp value (as documentation says: " A value of 0 prevents the IGMP membership report from being issued in response to the failover event.")
