From: Guojia Liao <redacted> 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.
