Subject: [PATCH net v2] net: cxgb3_main: disable napi when bind qsets failed in cxgb_up()

When failed to bind qsets in cxgb_up() for opening device, napi isn't
disabled. When open cxgb3 device next time, it will trigger a BUG_ON()
in napi_enable(). Compile tested only.

Fixes: 48c4b6dbb7e2 ("cxgb3 - fix port up/down error path")
