objtool: Print data address for "!ENDBR" data warnings
When a "!ENDBR" warning is reported for a data section, objtool just
prints the text address of the relocation target twice, without giving
any clues about the location of the original data reference:
vmlinux.o: warning: objtool: dcbnl_netdevice_event()+0x0: .text+0xb64680: data relocation to !ENDBR: dcbnl_netdevice_event+0x0
Instead, print the address of the data reference, in addition to the
address of the relocation target.
vmlinux.o: warning: objtool: dcbnl_nb+0x0: .data..read_mostly+0xe260: data relocation to !ENDBR: dcbnl_netdevice_event+0x0
Fixes: 89bc853eae4a ("objtool: Find unused ENDBR instructions")
