[PATCH] sunrpc: avoid -Wformat-security warning

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Using a non-constant string as an sprintf-style is potentially dangerous:

net/sunrpc/svc.c: In function 'param_get_pool_mode':
net/sunrpc/svc.c:164:32: error: format not a string literal and no format arguments [-Werror=format-security]

Use a literal "%s" format instead.

Fixes: 5f71f3c32553 ("sunrpc: refactor pool_mode setting code")
