drm/gem: Fix sphinx warnings

Sphinx really wants colons after arguments :/

Fixes the following warnings:
drm_gem.c:1384: warning: Function parameter or member 'fence_array' not described in 'drm_gem_fence_array_add'
drm_gem.c:1384: warning: Function parameter or member 'fence' not described in 'drm_gem_fence_array_add'
drm_gem.c:1435: warning: Function parameter or member 'fence_array' not described in 'drm_gem_fence_array_add_implicit'
drm_gem.c:1435: warning: Function parameter or member 'obj' not described in 'drm_gem_fence_array_add_implicit'
drm_gem.c:1435: warning: Function parameter or member 'write' not described in 'drm_gem_fence_array_add_implicit'

Fixes: 5d5a179d3e90 ("drm: Add helpers for setting up an array of dma_fence dependencies.")
