If a bonding port gets released, a link status alarm callback still
referenced the ethdev port that may be reused later.
Cancel this callback when stopping the port.
Bugzilla ID: 1301
Fixes: a45b288ef21a ("bond: support link status polling")
Cc: stable@dpdk.org

Note: this issue was made apparent now that we release the ethdev port
shared mem, see 36c46e738120 ("ethdev: cleanup shared data with ...").

How about move this line in above {}.
Anyway, both OK for me

Is the cast to void * actually necessary?
