crypto: octeontx2 - remove errata workaround for CN10KB or CN10KA B0 chip.

Adds code to not execute CPT errata "when CPT_AF_DIAG[FLT_DIS] = 0 and a
CPT engine access to LLC/DRAM encounters  a fault/poison, a rare case
may result in unpredictable data being delivered to a CPT engine"
workaround on CN10KA B0/CN10KB HW as it is fixed on these chips.
