ice: Don't tx before switchdev is fully configured
[ Upstream commit 7aa529a69e92b9aff585e569d5003f7c15d8d60b ]
There is possibility that ice_eswitch_port_start_xmit might be
called while some resources are still not allocated which might
cause NULL pointer dereference. Fix this by checking if switchdev
configuration was finished.
