Daisuke Ogino d2857e79a2 procfs: return ENOENT on opening a being-removed proc entry 
Change the return value to ENOENT.  This return value is then returned
when opening the proc entry that have been removed.  For example,
open("/proc/bus/pci/XX/YY") when the corresponding device is being
hot-removed.
