xfrm: make xfrm modes builtin
after previous changes, xfrm_mode contains no function pointers anymore and all modules defining such struct contain no code except an init/exit functions to register the xfrm_mode struct with the xfrm core. Just place the xfrm modes core and remove the modules, the run-time xfrm_mode register/unregister functionality is removed. Before: text data bss dec filename 7523 200 2364 10087 net/xfrm/xfrm_input.o 40003 628 440 41071 net/xfrm/xfrm_state.o 15730338 6937080 4046908 26714326 vmlinux 7389 200 2364 9953 net/xfrm/xfrm_input.o 40574 656 440 41670 net/xfrm/xfrm_state.o 15730084 6937068 4046908 26714060 vmlinux The xfrm*_mode_{transport,tunnel,beet} modules are gone. v2: replace CONFIG_INET6_XFRM_MODE_* IS_ENABLED guards with CONFIG_IPV6 ones rather than removing them.
