Fix mxcfb driver probe fail
    
Fix commit Add device tree property unblank_delay to mxc_ipuv3_fb.c
with id : 094fb2a37cab175bbb9b699a56f6c48dab3510d0

The mxcfb_get_of_property function returned an error code if the device
tree property "unblank_delay" was not set and the mxcfb driver failed to
probe.
Now the error variable gets set to zero after the of_proerty_read.
