igb: Fix string truncation warnings in igb_set_fw_version

Commit 1978d3ead82c (“intel: fix string truncation warnings”)
fixes ‘-Wformat-truncation=’ warnings in igb_main.c by using kasprintf.

drivers/net/ethernet/intel/igb/igb_main.c:3092:53: warning:‘%d’ directive output may be truncated writing between 1 and 5 bytes into a region of size between 1 and 13 [-Wformat-truncation=]
3092 | “%d.%d, 0x%08x, %d.%d.%d”,
| ^~
drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note:directive argument in the range [0, 65535]
3092 | “%d.%d, 0x%08x, %d.%d.%d”,
| ^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note:directive argument in the range [0, 65535]
drivers/net/ethernet/intel/igb/igb_main.c:3090:25: note:‘snprintf’ output between 23 and 43 bytes into a destination of size 32

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure.

Fix this warning by using a larger space for adapter->fw_version,
and then fall back and continue to use snprintf.
