SUNRPC: Address kbuild warning in net/sunrpc/debugfs.c
Cross-compile test on ARCH=mn10300:
In file included from include/linux/list.h:8:0,

net/sunrpc/debugfs.c: In function 'fault_disconnect_write':
include/linux/kernel.h:723:17: warning: comparison of distinct pointer
types lacks a cast
(void) (&_min1 == &_min2); \
^
>> net/sunrpc/debugfs.c:307:8: note: in expansion of macro 'min'
len = min(len, sizeof(buffer) - 1);
Fixes: ('SUNRPC: Transport fault injection')
