[RESEND 03/15] drm/vkms/vkms_composer: Fix a few different kerneldoc formatting

[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/vkms/vkms_composer.c:41: warning: Function parameter or member 'frame_info' not described in 'pre_mul_alpha_blend'
 drivers/gpu/drm/vkms/vkms_composer.c:41: warning: Excess function parameter 'src_frame_info' description in 'pre_mul_alpha_blend'
 drivers/gpu/drm/vkms/vkms_composer.c:72: warning: Cannot understand  * @wb_frame_info: The writeback frame buffer metadata
