Rename the function local variable i -> sg_cnt so we can get rid of the
shadow variable compilation warning:-

drivers/target//target_core_sbc.c: In function ‘compare_and_write_do_cmp’:
drivers/target//target_core_sbc.c:475:17: warning: declaration of ‘i’ shadows a previous local [-Wshadow]
    unsigned int i;
                 ^
drivers/target//target_core_sbc.c:451:6: note: shadowed declaration is here
  int i;
      ^
