NFSD: Put cache get-reqs dump attrs under reply
The new get-reqs dump operations added to sunrpc_cache.yaml and nfsd.yaml place the "requests" nested attribute under dump.request. A netlink dump carries an empty request; its payload travels back in the reply. Because the spec names no reply attributes, the YNL C code generator synthesizes a forward reference to a <op>_rsp struct that is never defined, breaking any consumer of these specs. This first surfaced when Thorsten Leemhuis built tools/net/ynl against -next: nfsd-user.h:746: error: field 'obj' has incomplete type struct nfsd_svc_export_get_reqs_rsp obj ... nfsd-user.h:826: error: field 'obj' has incomplete type struct nfsd_expkey_get_reqs_rsp obj ... nfsd-user.c:1211: error: 'nfsd_svc_export_get_reqs_rsp_parse' undeclared sunrpc_cache.yaml has the same defect in ip-map-get-reqs and unix-gid-get-reqs, but nfsd.yaml errors out first in the Makefile's alphabetical build order and hides the sunrpc failures. These bugs were introduced by incorrect merge conflict resolution.
