767b4f0e59 main: Enable the api-socket to be passed as an fd
To avoid race issues where the api-socket may not be created by the
time a cloud-hypervisor caller is ready to look for it, enable the
caller to pass the api-socket fd directly.

Avoid breaking current callers by allowing the --api-socket path to be
passed as it is now in addition to through the path argument.

Windows guests read this field upon PCI device ejection. Let's make sure
we don't return an error as this is valid. We simply return an empty u32
since the ejection is done right away upon write access, which means
there's no pending ejection that might be reported to the guest.

Here is the error that was shown during PCI device removal:

b92fe648e9 vmm: cpu: Disable KVM_FEATURE_ASYNC_PF_INT in CPUID
By disabling this KVM feature, we prevent the guest from using APF
(Asynchronous Page Fault) mechanism. The kernel has recently switched to
using interrupts to notify about a page being ready, but for some
reasons, this is causing unexpected behavior with Cloud Hypervisor, as
it will make the vcpu thread spin at 100%.

While investigating the issue, it's better to disable the KVM feature to
prevent 100% CPU usage in some cases.
