So we can use this function on other devices, such as vDPA device. - Add a new function vfio_get_xlat_addr in vfio/common.c, and it will check whether the memory is backed by a discard manager. then device can have its own warning.

Restructure the code such that a failure of this function triggers an error and clean up the remainder of the function, including updating an outdated comment that had drifted from its relevant line of code and using host page size for a default for better compatibility on non-4KB systems.

"device_state" and "vm_running" are initialized to 0, indicating that VFIO device is_STOP and VM is not-running. The initialization value is incorrect. According to the agreement, default state of VFIO device is _RUNNING. And if a VFIO device is hot-plugged while the VM is running, "vm_running" should be 1. This patch fixes it.
