video: ipuv3: Fix error handling when getting the display

Browse source 
The code checks that uclass_first_device returned a device but the
returned value that is assigned is never used. Use
uclass_first_device_err instead, and move the error return outside of
the if block.

Fixes: f4ec1ae08e ("mxc_ipuv3_fb.c: call display_enable")
