Commit 65b32f801bfb ("uapi: move IPPROTO_L2TP to in.h") moved the
definition of IPPROTO_L2TP from a define to an enum, but since
__stringify doesn't work properly with enums, we ended up breaking the
modalias strings for the l2tp modules:
$ modinfo l2tp_ip l2tp_ip6 | grep alias
alias: net-pf-2-proto-IPPROTO_L2TP
alias: net-pf-2-proto-2-type-IPPROTO_L2TP
alias: net-pf-10-proto-IPPROTO_L2TP
alias: net-pf-10-proto-2-type-IPPROTO_L2TP
Use the resolved number directly in MODULE_ALIAS_*() macros (as we
already do with SOCK_DGRAM) to fix the alias strings:
$ modinfo l2tp_ip l2tp_ip6 | grep alias
alias: net-pf-2-proto-115
alias: net-pf-2-proto-115-type-2
alias: net-pf-10-proto-115
alias: net-pf-10-proto-115-type-2
Moreover, fix the ordering of the parameters passed to
MODULE_ALIAS_NET_PF_PROTO_TYPE() by switching proto and type.

Thanks!
Just to be explicit to the maintainers, this patch is for the net tree
(next time, you can use [PATCH net] to make that clear).
