r302550:

Deobfuscate cleanup path in clnt_dg_create(..)

Similar to r300836 and r301800, cl and cu will always be non-NULL as they're
allocated using the mem_alloc routines, which always use
malloc(..., M_WAITOK).

Deobfuscating the cleanup path fixes a leak where if cl was NULL and
cu was not, cu would not be free'd, and also removes a duplicate test for
cl not being NULL.

r302551:

Deobfuscate cleanup path in clnt_vc_create(..)

Similar to r300836, r301800, and r302550, cl and ct will always
be non-NULL as they're allocated using the mem_alloc routines,
which always use malloc(..., M_WAITOK).

CID: 1007342

r302552:

Convert svc_xprt_alloc(..) and svc_xprt_free(..)'s prototypes to
ANSI C style prototypes

r302553:

Don't test for xpt not being NULL before calling svc_xprt_free(..)

svc_xprt_alloc(..) will always return initialized memory as it uses
mem_alloc(..) under the covers, which uses malloc(.., M_WAITOK, ..).
