Osama Abdelkader b28cf21422 drm/bridge: megachips: remove bridge when irq request fails 
commit d45d5c819f upstream.

If devm_request_threaded_irq() fails after drm_bridge_add(), remove the
bridge before returning.

Keep drm_bridge_add() rather than devm_drm_bridge_add(): registration is
tied to the STDP4028 device while ge_b850v3_register() may complete from
either I2C probe; devm would not unwind the bridge if the other client's
probe fails.
