Rui Chang 2d53d32872 nvmf/vfio-user: Fix doorbell polling not working on some ARM platform 
On aarch64 platforms, doorbells update from guest VM may not be seen
on SPDK target side. This is because there is memory type mismatch
situation here. That is on guest VM side, the doorbells are treated as
device memory while on SPDK target side, it is treated as normal
memory. And this situation cause problem on ARM platform.
Refer to "https://developer.arm.com/documentation/102376/0100/
Memory-aliasing-and-mismatched-memory-types". Only using spdk_mb()
cannot fix this. Use "dc civac" to invalidate cache may solve this.

Profiling data did not show big performance degradataion.
