All NLMv3 server-side procedures now dispatch through xdrgen-generated encoder and decoder functions, leaving the hand-written XDR processing in fs/lockd/xdr.c with no remaining callers. Remove fs/lockd/xdr.c, the fs/lockd/svcxdr.h header it included, the Makefile entry, and the now-unused nlmsvc_decode_* / nlmsvc_encode_* prototypes from fs/lockd/xdr.h. The structure definitions and status code macros in xdr.h are retained as they are still used by the client-side code.
