drm/bridge: waveshare-dsi: Fix bailout for devm_drm_bridge_alloc()
devm_drm_bridge_alloc() returns ERR_PTR on failure instead of a
NULL pointer, so use IS_ERR() to check the returned pointer and
turn proper error code on failure by using PTR_ERR().
Fixes: dbdea37add13 ("drm: bridge: Add waveshare DSI2DPI unit driver")
