drm/client: Switch drm_client_buffer_delete() to unlocked drm_gem_vunmap

Browse Source 
The drm_client_buffer_delete() wasn't switched to unlocked GEM vunmapping
by accident when rest of drm_client code transitioned to the unlocked
variants of the vmapping functions. Make drm_client_buffer_delete() use
the unlocked variant. This fixes lockdep warning splat about missing
reservation lock when framebuffer is released.
