libuci: refactor uci_get_errorstr

* replace strange error_info[0]=0 with complete zeroing of the buffer
* make the function body shorter and more clear, decrease indentation
  levels
* fix format string warnings:

   libuci.c:172:24: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
   libuci.c:181:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
