[PATCH v1] xdrgen: Address some checkpatch whitespace complaints

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

This is a roll-up of three template fixes that eliminate noise from
checkpatch output so that it's easier to spot non-trivial problems.

To follow conventional kernel C style, when a union declaration is
marked with "pragma public", there should be a blank line between
the emitted "union xxx { ... };" and the decoder and encoder
function declarations.

---

CHECK: Please use a blank line after function/struct/union/enum declarations
+};
+typedef enum createmode3 createmode3;

Make xdrgen output more "checkpatch friendly" -- add a blank line
after enum definitions.

---

CHECK: Please don't use multiple blank lines
+
+

Eliminate a source of checkpatch.pl warnings in xdrgen-generated
C header files.
