Check return values when storing peripheral info

Without these checks, in rare cases, this could trigger huddly-updater
to perform a control transfer to a device that didn't exist and thus
segfault.

BUG=chromium:752708
TEST=Plug/unplug the device until "failed to store peripheral info" is
written to /var/log/messages. A segfault should not occur.
