libsmbconf: Avoid initial declaration inside 'for' loop

Building Samba on CentOS 7 with GCC version 4.8.5 results in the
following error:

[2725/3398] Compiling libcli/echo/tests/echo.c
../../lib/smbconf/pysmbconf.c: In function 'py_from_smbconf_service':
../../lib/smbconf/pysmbconf.c:72:2: error: 'for' loop initial
                               declarations are only allowed in C99 mode
  for (uint32_t i = 0; i < svc->num_params; i++) {
  ^
../../lib/smbconf/pysmbconf.c:72:2: note: use option -std=c99 or
                                         -std=gnu99 to compile your code

  ^

Therefore declare variables right at the start aligning to default C90
standard available with GCC version on CentOS 7.
