cmd: ini: Fix build warning

Building U-Boot with CMD_INI=y result in following build warning:

  cmd/ini.c: In function 'memgets':
  include/linux/kernel.h:184:24: warning: comparison of distinct pointer types lacks a cast
    184 |         (void) (&_min1 == &_min2);              \
        |                        ^~
  cmd/ini.c:92:15: note: in expansion of macro 'min'
     92 |         len = min((end - *mem) + newline, num);
        |               ^~~

Fix this by adding an int cast to the pointer arithmetic result.
