r8169: don't use MSI-X on RTL8106e
[ Upstream commit 7bb05b85bc2d1a1b647b91424b2ed4a18e6ecd81 ]
Found the ethernet network on ASUS X441UAR doesn't come back on resume
from suspend when using MSI-X. The chip is RTL8106e - version 39.

Capabilities: <access denied>
Kernel driver in use: r8169
Kernel modules: r8169
Falling back to MSI fixes the issue.
