r8169: fix packet truncation after S4 resume on RTL8168H/RTL8111H

[ Upstream commit 70f92ab9 ]

After resume from S4 (hibernate), RTL8168H/RTL8111H truncates incoming
packets. Packet captures show messages like "IP truncated-ip - 146 bytes
missing!".

The issue is caused by RxConfig not being properly re-initialized after
resume. Re-initializing the RxConfig register before the chip
re-initialization sequence avoids the truncation and restores correct
packet reception.

This follows the same pattern as commit ef9da46d ("r8169: fix data
corruption issue on RTL8402").
