[dpdk-dev] [PATCH 1/2] net/avp: fix gcc 10 maybe-uninitialized warning

[Kevin Traynor]

gcc 10.0.1 reports:

../drivers/net/avp/avp_ethdev.c: In function ‘avp_xmit_scattered_pkts’:
../drivers/net/avp/avp_ethdev.c:1791:24:
warning: ‘avp_bufs[count]’ may be used uninitialized in this function 
[-Wmaybe-uninitialized]
 1791 |   tx_bufs[i] = avp_bufs[count];
      |                ~~~~~~~~^~~~~~~
../drivers/net/avp/avp_ethdev.c:1791:24:
warning: ‘avp_bufs[count]’ may be used uninitialized in this function 
[-Wmaybe-uninitialized]

Fix by intializing the array.
