94010fa0dd07e8b904e7c6b6589f15573008ab15 introduced MSI interrupts mode
support, which seemed safe enough with RTL8188EE and RTL8723BE as
RealTek's testing results, but some users reported their RTL8188EE
modules could not connect to any wireless network after the MSI mode was
enabled by Ubuntu 14.04.

So, let's fallback to pin-based mode until rtlwifi's MSI support get
good compatibility.
