Grygorii Strashko ae03d189ba net: ethernet: ti: am65-cpsw: fix crash in am65_cpsw_port_offload_fwd_mark_update() 
The am65_cpsw_port_offload_fwd_mark_update() causes NULL exception crash
when there is at least one disabled port and any other port added to the
bridge first time.

Unable to handle kernel NULL pointer dereference at virtual address 0000000000000858
pc : am65_cpsw_port_offload_fwd_mark_update+0x54/0x68
lr : am65_cpsw_netdevice_event+0x8c/0xf0
Call trace:
am65_cpsw_port_offload_fwd_mark_update+0x54/0x68

netdev_master_upper_dev_link+0x1c/0x28
br_add_if+0x3f0/0x6d0 [bridge]

Fix it by adding proper check for port->ndev != NULL.
