Various fixes and improvements for the dpaa2 net driver and fslmc bus.

Patches 1-6 fix resource leaks on port close, error paths, link status
and devargs propagation on hotplug.

Patches 7-14 fix additional bugs: spurious VLAN insertion, error packet
dump crash, packet type classification, checksum offload flags, software
taildrop buffer access, burst mode info reporting, SG table walk bounds,
and MAC stats DMA allocation.

Patch 15 is a minor cleanup in the link status area.

Patches 16-17 add devargs alternatives for getenv-based configuration
of taildrop and data stashing options.

Changes since v1:
- Add Cc: stable@dpdk.org on patches with Fixes: tags (Stephen)
- Reorder series: fixes first, then improvements (Stephen)
- Patch 2: squash with former patch 4 (Hemant)
- Patch 6: move devargs refresh from plug to scan rescan path (David)
- Patch 17: keep getenv for backward compatibility, add devargs as
alternative instead of replacement
- Drop former patch 11 (bus/fslmc: remove dead blocklist check) to
avoid disaligning with other buses (David)
- New patches 8, 11-14 fixing issues reported by Stephen
- New patches 7, 9-10 fixing VLAN insertion and packet classification
issues
