net/qede: fix flow director for IPv6 filter

Browse Source 
- PMD does not fill vtc_flow field of IPv6 header while
  constructing a packet for IPv6 filter. Hence filter was
  not getting applied properly.
- IPv6 addresses got swapped while copying src and dst addresses.
- Same issue with UDP and TCP port ids.

Fixes: 622075356e8f ("net/qede: support ntuple and flow director filter")
