Subject: [PATCH] net/bonding: do not clear active slave count

[ upstream commit 69bce062132bd2b4a943fafbb710215a7999d198 ]

When the bond PMD is stopped, the active slave count is reset.
For 802.3ad mode this potentially leaks memory and clears state since
a second sequential activate_slave() will occur when the bond PMD is
restarted and the LSC callback is triggered while the active slave
count is 0. To fix this, don't clear the active slave count when
stopping. Only deactivate_slave() should be used to clear the slaves.

Fixes: 2efb58cbab6e ("bond: new link bonding library")
