[Jiawen Wu <jiawenwu@trustnetic.com>]

Fix some memory leaks caused by not release resource in time.

Fixes: e1698e383c2a ("net/txgbe: add device init and uninit")
Fixes: 635c21354f9a ("net/txgbe: add flow director filter init and uninit")
Fixes: c13f84a71b2d ("net/txgbe: add L2 tunnel filter init and uninit")
Fixes: 3a123ba60a71 ("net/txgbe: support VF start and stop")
Fixes: 039b769f7c01 ("net/txgbe: support VF MAC address")
Fixes: 226bf98eda87 ("net/txgbe: add Rx and Tx queues setup and release")
