net/ngbe: fix Tx hang on queue disable

Add commands requesting firmware to enable or disable PCIe bus master.
Disable PCIe master access to clear BME when stop hardware, and verify
there are no pending requests.

Move disabling Tx queue after disabling PCIe bus master, to ensure that
there are no packets left to cause Tx hang.
