Yoshihiro Shimoda 044e7097e8 net: renesas: sh_eth: Fix freeing wrong tx descriptor 
[ Upstream commit 0341d5e3d1 ]

The cur_tx counter must be incremented after TACT bit of
txdesc->status was set. However, a CPU is possible to reorder
instructions and/or memory accesses between cur_tx and
txdesc->status. And then, if TX interrupt happened at such a
timing, the sh_eth_tx_free() may free the descriptor wrongly.
So, add wmb() before cur_tx++.
Otherwise NETDEV WATCHDOG timeout is possible to happen.
