[PATCH v2 1/2] drm/msm/dsi: use msm_gem_kernel_put to free TX buffer

[Dmitry Baryshkov]

Use exiting function to free the allocated GEM object instead of
open-coding it. This has a bonus of internally calling
msm_gem_put_vaddr() to compensate for msm_gem_get_vaddr() in
msm_get_kernel_new().

Fixes: 1e29dff00400 ("drm/msm: Add a common function to free kernel buffer 
objects")
