We currently cannot flush more than ~64 addresses on a device, with
strange status.

# ip -stats addr flush dev eth3
Failed to send flush request: Success
Flush terminated

Problem is in rtnl_send_check(), where a return -1; is misplaced.

After patch, we can flush 64000 addresses without any problem.

# ip -stats addr flush dev eth3

*** Round 1, deleting 32338 addresses ***

*** Round 2, deleting 16168 addresses ***

*** Round 3, deleting 8082 addresses ***

*** Round 4, deleting 4058 addresses ***

*** Round 5, deleting 2028 addresses ***

*** Round 6, deleting 918 addresses ***

*** Round 7, deleting 278 addresses ***

*** Round 8, deleting 130 addresses ***
*** Flush is complete after 8 rounds ***
