[PATCH 1/2] svcrpc: fix compile warning about unused variable 'buf'

[Mika Westerberg]

Commit 7032a3dd923 (svcrpc: demote some printks to a dprintk) changed the
printk to a dprintk() macro. Since the macro is not always available we get
following compile warning:

net/sunrpc/svc.c: In function âsvc_printkâ:
net/sunrpc/svc.c:1050:8: warning: unused variable âbufâ [-Wunused-variable]

Fix this by marking the 'buf' with __maybe_unused.

In addition make checkpatch.pl happy by removing space before tab after
'char'.
