net: cpsw: disable napi in cpsw_ndo_open()

Browse source 
[ Upstream commit 6d47b53fb3f363a74538a1dbd09954af3d8d4131 ]

When failed to create xdp rxqs or fill rx channels in cpsw_ndo_open() for
opening device, napi isn't disabled. When open cpsw device next time, it
will report a invalid opcode issue. Compiled tested only.
