[PATCH v2 1/1] lockd: Change nsm_use_hostnames from bool to u32

[Jia He]

nsm_use_hostnames is a module paramter 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 changes the type definition of nsm_use_hostnames.

V2: Changes extern type in lockd.h
