Subject: net: hns3: cleanup a format-truncation warning
Patch-mainline: v5.5-rc1
Git-commit: e4b806edfabd43853d365a9fcaf238cf10c3c4ab
References: bsc#1154353
In hns3_nic_init_irq(), when '*_int_idx' has more than 9 digits
and the length of netdev's name is IFNAMSIZ, the total length
of final name will be bigger the HNAE3_INT_NAME_LEN - 1, even
though '*_int_idx' will never have such large value, but the
compiler gives a format-truncation warning for this case.
So this patch just enlarges the length to avoid this warning.
