Improve the error message when writing a tree

Print the error reported by libc, instead of its translation into an
error code returned by the serialization function. This will provide
details of what went wrong at the system level.

Note that the deserialization function displays the error as reported by
the function's return code, not the libc error. This is because in this
situation, the end of the file can be reached without being considered
an error, even though it is indeed an error from the function's point of
view.
