of: fix of_device_get_modalias returned length when truncating buffers
If the length of the modalias is greater than the buffer size, then the
modalias is truncated. However the untruncated length is returned which
will cause an error. Fix this to return the truncated length. If an error
in the case was desired, then then we should just return -ENOMEM.
The reality is no device will ever have 4KB of compatible strings to hit
this case.
