attrib-server: Allow zero length attribute update attrib_db_update always fails when g_try_realloc returns NULL, not taking into account that the length passed to g_try_realloc could be zero. In this case, g_try_realloc frees the currently allocated memory and returns NULL. As a result, not only will attrib_db_update fail needlessly, a use-after-free could occur as the attribute's length will still hold the length of the freed buffer. Fix this by only returning an error if the length is non-zero.
