lockd: change the proc_handler for nsm_use_hostnames

Browse Source 
[ Upstream commit d02a3a2cb25d384005a6e3446a445013342024b7 ]

nsm_use_hostnames is a module parameter and it will be exported to sysctl
procfs. This is to let user sometimes change it from userspace. But the
minimal unit for sysctl procfs read/write it sizeof(int).
In big endian system, the converting from/to  bool to/from int will cause
error for proc items.

This patch use a new proc_handler proc_dobool to fix it.
