Fedor Tokarev 7941ee42dc net: sunrpc: Fix 'snprintf' return value check in 'do_xprt_debugfs' 
[ Upstream commit 35a6d39672 ]

'snprintf' returns the number of characters which would have been written
if enough space had been available, excluding the terminating null byte.
Thus, the return value of 'sizeof(buf)' means that the last character
has been dropped.
