e1000e: Fix -Wformat-truncation warnings
[ Upstream commit 135e7245479addc6b1f5d031e3d7e2ddb3d2b109 ]
Provide precision hints to snprintf() since we know the destination
buffer size of the RX/TX ring names are IFNAMSIZ + 5 - 1. This fixes the
following warnings:
drivers/net/ethernet/intel/e1000e/netdev.c: In function
'e1000_request_msix':

output may be truncated before the last format character
[-Wformat-truncation=]
"%s-rx-0", netdev->name);
^
