coredump: Move dump_emit_page() to kill unused warning

Browse Source 
commit 9c7417b5ec440242bb5b64521acd53d4e19130c1 upstream.

If CONFIG_ELF_CORE is not set:

    fs/coredump.c:835:12: error: ‘dump_emit_page’ defined but not used [-Werror=unused-function]
      835 | static int dump_emit_page(struct coredump_params *cprm, struct page *page)
          |            ^~~~~~~~~~~~~~

Fix this by moving dump_emit_page() inside the existing section
protected by #ifdef CONFIG_ELF_CORE.

Fixes: 06bbaa6dc5 ("[coredump] don't use __kernel_write() on kmap_local_page()")
