[PATCH 2/2] utils: ipu3: Fix return value check on file output

[Kieran Bingham]

The data parsed by ipu3-unpack is written out using the write() c
library call, but the error code is incorrectly checked which misses the
single erroroneous return value returned by the function.

Fix it to explicitly check against the error code.
