octeontx2-af: Unlock NDCX_AF_BANKX_LINEX_METADATA during NDC fault/lockerror/poison.

commit 699e13b4a0a6a752678a56a4b539f70a94b08d4d from
git@git.assembla.com:cavium/WindRiver.linux.git

NDCX_AF_BANKX_LINEX_METADATA lock bit needs to be cleared when NDC
detects some fault/lockerror/poison to avoid hardware errata. Otherwise
NDC way gets into an illegal state of not valid but locked.
