Those data path loggers weren't used anywhere after the definition. This commit uses the generic RTE_ETHDEV_DEBUG_RX and RTE_ETHDEV_DEBUG_TX flags to define PMD_TX_LOG and PMD_RX_LOG which are now being used on the data path. The PMD_TX_FREE_LOG was removed, as it has no usage in the current version of the driver. RTE_ETH_DEBUG_[TR]X now wraps extra checks for the driver state in the IO path - this saves extra conditionals on the hot path. ena_com logger is no longer optional (previously it had to be explicitly enabled by defining this flag: RTE_LIBRTE_ENA_COM_DEBUG). Having this logger optional makes tracing of ena_com errors much harder. Due to ena_com design, it's impossible to separate IO path logs from the management path logs, so for now they will be always enabled. Default levels for the affected loggers were modified. Hot path loggers are initialized with the default level of DEBUG instead of NOTICE, as they have to be explicitly enabled. ena_com logging level was reduced from NOTICE to WARNING - as it's no longer optional, the driver should report just a warnings in the ena_com layer.
