[PATCH] drm/bridge: analogix_dp: Fix a NULL vs IS_ERR() check in probe()

[Dan Carpenter]

The devm_drm_bridge_alloc() function doesn't return NULL pointers, it
returns error pointers.  Update the error checking to match.

Fixes: 48f05c3b4b70 ("drm/bridge: analogix_dp: Use devm_drm_bridge_alloc() API")
