Release locked buffer when it fails to acquire graphics buffer

The JNI buffer in ImageReader_imageSetup is not released when
it fails to acquire graphics buffer. After all JNI buffers are
exhausted, ACQUIRE_MAX_IMAGES will be returned and leads to
error. The JNI buffer should be released when it fails to acquire
graphics buffer.

Keyguard: Ensure that a widget and page is attached before attaching the ChallengeLayout.OnBouncerStateChangedListener

otherwise it can result in a NPE due that the page was not loaded. Especially on low end
devices this can happen (see zoomOutToBouncer() method @KeyguardWidgetPager)

Structure device not freed in error case

In case of an error in the call usb_device_get_fd()
the memory created by usb_open_device() is never
freed.

Added a call to usb_device_close in case of error to
release the allocated memory.

Remove java.io.tmpdir assignment in AndroidRuntime.

This value is overridden by the framework anyway
(see ActivityThread.handleBindApplication). Besides,
it doesn't seem like a great idea to let tools clutter
/sdcard/ with temp files.
