vfio/pci: clean up a type in vfio_pci_ioctl_pci_hot_reset_groups()
The "array_count" value comes from the copy_from_user() in
vfio_pci_ioctl_pci_hot_reset(). If the user passes a value larger than
INT_MAX then we'll pass a negative value to kcalloc() which triggers an
allocation failure and a stack trace.
It's better to make the type unsigned so that if (array_count > count)
returns -EINVAL instead.
