[PATCH next] drm/bridge: synopsys: Return correct variable in dw_dp_bind()

[Dan Carpenter]

There is a copy and paste bug here so we accidentally return "ret"
which is zero instead of "dp->irq" which is an error code.  Return
the correct variable.

Fixes: 86eecc3a9c2e ("drm/bridge: synopsys: Add DW DPTX Controller support 
library")
