drm/msm/a6xx: Fix kvzalloc vs state_kcalloc usage
adreno_show_object() is a trap! It will re-allocate the pointer it is
passed on first call, when the data is ascii85 encoded, using kvmalloc/
kvfree(). Which means the data *passed* to it must be kvmalloc'd, ie.
we cannot use the state_kcalloc() helper.
This partially reverts commit ec8f1813bf8d ("drm/msm/a6xx: Replace
kcalloc() with kvzalloc()"), but adds the missing kvfree() to fix the
memory leak that was present previously. And adds a warning comment.
Fixes: ec8f1813bf8d ("drm/msm/a6xx: Replace kcalloc() with kvzalloc()")
Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/20
