[PATCH net-next 1/3] ptp: ocp: Fix uninitialized variable warning spotted by clang.

[Jonathan Lemon <jonathan.lemon@gmail.com>]

If attempting to flash the firmware with a blob of size 0,
the entire write loop is skipped and the uninitialized err
is returned.  Fix by setting to 0 first.

Also remove a now-unused error handling statement.
