We pass be_path to tapdisk_destroy but we've already deleted it so it fails to read tapdisk-params. However it appears that we need to destroy the tap device after tearing down xenstore, to avoid the leak reported by Greg Wettstein in <201207312141.q6VLfJje012656@wind.enjellic.com>. So read the tapdisk-params in the cleanup transaction, before the remove, and pass that down to destroy_tapdisk instead. tapdisk-params may of course be NULL if the device isn't a tap device. There is no need to tear down the tap device from libxl__initiate_device_remove since this ultimately calls libxl__device_destroy. Propagate and log errors from libxl__device_destroy_tapdisk.
