config: flip return value of write_section() 

d9bd4cbb9c (config: flip return value of store_write_*()) made
write_section() follow the convention of write(2) to return -1 on error
and the number of written bytes on success.  3b48045c6c (Merge branch
'sd/branch-copy') changed it back to returning 0 on error and 1 on
success, but left its callers still checking for negative values.

Let write_section() follow the convention of write(2) again to meet the
expectations of its callers.
