drm/bridge: imx8qxp-pxl2dpi: Fix NULL pointer dereference in imx8qxp_pxl2dpi_bridge_destroy()
Pointer bridge->driver_private in imx8qxp_pxl2dpi_bridge_destroy()
is NULL when imx8qxp_pxl2dpi_bridge_probe() returns error, because
the pointer is initialized only when imx8qxp_pxl2dpi_bridge_probe()
returns 0. The NULL pointer would be set to pointer p2d and then
NULL pointer p2d would be dereferenced. Fix this by returning early
from imx8qxp_pxl2dpi_bridge_destroy() if !p2d is true.
