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: 06bbaa6 ("[coredump] don't use __kernel_write() on kmap_local_page()") Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Al Viro <[email protected]>
