amd-xgbe: Avoid potential string truncation in name
Build with W=1 were warning about a potential string truncation:
drivers/net/ethernet/amd/xgbe/xgbe-drv.c: In function 'xgbe_alloc_channels':
drivers/net/ethernet/amd/xgbe/xgbe-drv.c:211:73: warning: '%u' directive output may be truncated writing between 1 and 10 bytes into a region of size 8 [-Wformat-truncation=]
211 | snprintf(channel->name, sizeof(channel->name), "channel-%u", i);
| ^~
drivers/net/ethernet/amd/xgbe/xgbe-drv.c:211:64: note: directive argument in the range [0, 4294967294]
211 | snprintf(channel->name, sizeof(channel->name), "channel-%u", i);
| ^~~~~~~~~~~~
drivers/net/ethernet/amd/xgbe/xgbe-drv.c:211:17: note: 'snprintf' output between 10 and 19 bytes into a destination of size 16
211 | snprintf(channel->name, sizeof(channel->name), "channel-%u", i);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Increase the size of the "name" buffer to handle the full format range.
