Add drm_panic module for vmwgfx stdu mode so that panic screen can be
displayed on panic. Since implemented by writing to VRAM and switching
back to legacy mode, it would expect to work in all DU modes.

The `size` argument in the `qxl_alloc_release_reserved` function is
currently unused and has no effect on the function's logic. So remove
this argument to clean up the code. No functional changes are expected.

virtio drm_panic supports only vmapped shmem BO because there is no
atomic vmap feature. Now atomic_vmap is supported, so drm_panic tries to
vmap addr if it is not mapped.

Some drivers can use vmap in drm_panic, however, vmap is sleepable and
takes locks. Since drm_panic will vmap in panic handler, atomic_vmap
requests pages with GFP_ATOMIC and maps KVA without locks and sleep.
