Igor Russkikh 31295e1ac6 net: atlantic: fix double free in ring reinit logic 
[ Upstream commit 7bb26ea74aa86fdf894b7dbd8c5712c5b4187da7 ]

Driver has a logic leak in ring data allocation/free,
where double free may happen in aq_ring_free if system is under
stress and driver init/deinit is happening.

The probability is higher to get this during suspend/resume cycle.

Verification was done simulating same conditions with

    stress -m 2000 --vm-bytes 20M --vm-hang 10 --backoff 1000
    while true; do sudo ifconfig enp1s0 down; sudo ifconfig enp1s0 up; done

Fixed by explicitly clearing pointers to NULL on deallocation
