coredump: Move dump_emit_page() to kill unused warning
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: 06bbaa6dc53cb720 ("[coredump] don't use __kernel_write() on kmap_local_page()")
