netdev: preserve NETIF_F_ALL_FOR_ALL across TSO updates
[ Upstream commit 02d1e1a3f9239cdb3ecf2c6d365fb959d1bf39df ]
Directly increment the TSO features incurs a side effect: it will also
directly clear the flags in NETIF_F_ALL_FOR_ALL on the master device,
which can cause issues such as the inability to enable the nocache copy
feature on the bonding driver.
The fix is to include NETIF_F_ALL_FOR_ALL in the update mask, thereby
preventing it from being cleared.
Fixes: b0ce3508b25e ("bonding: allow TSO being set on bonding master")
