[PATCH] drm/fb_dma: Fix parameter name in htmldocs

[Jocelyn Falempe <jfalempe@xxxxxxxxxx>]

The parameter name is 'sb' and not 'drm_scanout_buffer'.
It fixes the following warnings:

drivers/gpu/drm/drm_fb_dma_helper.c:166: warning: Excess function parameter 'drm_scanout_buffer' description in 'drm_fb_dma_get_scanout_buffer'
drivers/gpu/drm/drm_fb_dma_helper.c:166: warning: Function parameter or struct member 'sb' not described in 'drm_fb_dma_get_scanout_buffer'
drivers/gpu/drm/drm_fb_dma_helper.c:166: warning: Excess function parameter 'drm_scanout_buffer' description in 'drm_fb_dma_get_scanout_buffer'

Fixes: 879b3b6511fe ("drm/fb_dma: Add generic get_scanout_buffer() for drm_panic")
