Add reference count to registered mac address of station

Cherry-pick of aosp/2057192

When using mac randomization at Cloud Android, registered address
can be unintentionally removed when such control packet series are
received.

HWSIM_CMD_ADD_MAC_ADDR 02:15:b2:00:00:00, aa:bb:cc:dd:ee:ff
HWSIM_CMD_ADD_MAC_ADDR 02:15:b2:00:00:00, aa:bb:cc:dd:ee:ff
HWSIM_CMD_DEL_MAC_ADDR 02:15:b2:00:00:00, aa:bb:cc:dd:ee:ff

This can occur when scanning Wi-Fi APs at Cloud Android VM.

Add reference count at registered address to track addition and
deletion of mac address.
