[PATCH] net: sunrpc: sizeof('\0') is 4, not 1

[Ahelenia Ziemiańska]

To make it self-documenting, the referenced commit added the space
for the null terminator as sizeof('\0'). The message elaborates on
why only one byte is needed, so this is clearly a mistake.
Spell it as 1 /* NUL */ instead.

This is the only result for git grep "sizeof.'" in the tree.

Fixes: commit 1e360a60b24a ("SUNRPC: Address  buffer overrun in
 rpc_uaddr2sockaddr()")
