    migration: Fix order of function arguments

    This fixes a compiler error when higher warning levels are enabled:

    ../migration/postcopy-ram.c: In function ‘postcopy_temp_pages_setup’:
    ../migration/postcopy-ram.c:1483:50: error: ‘g_malloc0_n’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
     1483 |     mis->postcopy_tmp_pages = g_malloc0_n(sizeof(PostcopyTmpPage), channels);
          |                                                  ^~~~~~~~~~~~~~~
    ../migration/postcopy-ram.c:1483:50: note: earlier argument should specify number of elements, later size of each element

    Avoid also a related int/unsigned mismatch by fixing the type of
    two local variables.
