[PATCH v8 2/2] app/testpmd: get information about protocols defined in ddp profile

[Kirill Rybalchenko <kirill.rybalchenko@intel.com>]

Update 'ddp get info' command to display protocols defined in  a profile

v5
buff_size parameter in rte_pmd_i40e_get_ddp_info function call
always represents buffer size in bytes

v6
fix bug with wrong usage of buff_size parameter

v8
Fix code style warnings.
