devices: event_loop: delete hung-up events

When a file descriptor is returned from the poll context that has the
hungup flag set, it should no longer be polled. Remove it from both the
poll context and the map of handlers when hangup occurs.

Additionally, instead of stopping the whole event loop when an event
handler error occurs, just remove the failing event handler from the
watched set and continue. This should improve robustness of the USB
controller emulation.

BUG=chromium:1278424
TEST=Share USB device with Crostini via vmc, then physically unplug

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
