The ethtool app was allocating too little space for 64-bit registers which resulted in memory corruption. Removes hard-coded assumption that device registers are always 32 bits wide. The rte_eth_dev_get_reg_length and rte_eth_dev_get_reg_info callbacks did not provide register size to the app in any way while is needed to allocate correct number of bytes before retrieving registers using rte_eth_dev_get_reg. This commit changes rte_eth_dev_get_reg_info so that it can be used to retrieve both the number of registers and their width, and removes the now-redundant rte_eth_dev_get_reg_length.
