drm/vc4: Fix resource leak in 'vc4_get_hang_state_ioctl()' in error handling path
If one 'drm_gem_handle_create()' fails, we leak somes handles and some
memory.
In order to fix it:
- move the 'free(bo_state)' at the end of the function so that it is also
called in the eror handling path. This has the side effect to also try
to free it if the first 'kcalloc' fails. This is harmless.
- add a new label, err_delete_handle, in order to delete already
allocated handles in error handling path
- remove the now useless 'err' label
The way the code is now written will also delete the handles if the
'copy_to_user()' call fails.

- Add Laurent as bridge reviewer and Andrzej as bridge maintainer (Archit)
- Maintain new STM driver through -misc (Yannick)
- Misc doc improvements (as is tradition) (Daniel)
- Add driver-private objects to atomic state (Dhinakaran)
- Deprecate preclose hook in modern drivers (use postclose) (Daniel)
- Add hwmode to vblank struct. This fixes mode access in irq context and reduced
a bunch of boilerplate (Daniel)
Driver Changes:
- vc4: Add out-fence support to vc4 V3D rendering (Eric)
- stm: Add stm32f429 display hw and am-480272h3tmqw-t01h panel support (Yannick)
- vc4: Remove 256MB cma limit from vc4 (Eric)
- dw-hdmi: Disable audio when inactive, instead of always enabled (Romain)
- zte: Add support for VGA to the ZTE driver (Shawn)
- i915: Track DP MST bandwidth and check it in atomic_check (Dhinakaran)
- vgem: Enable gem dmabuf import iface to facilitate ion testing (Laura)
- vc4: Add support for Cygnus (new dt compat string + couple bug fixes) (Eric)
- pl111: Add driver for pl111 CLCD display controller (Eric/Tom)
- vgem: Subclass drm_device instead of standalone platform device (Chris)
