LOCKD: Fix a race when initialising nlmsvc_timeout
commit 06bed7d18c2c07b3e3eeadf4bd357f6e806618cc upstream.
This commit fixes a race whereby nlmclnt_init() first starts the lockd
daemon, and then calls nlm_bind_host() with the expectation that
nlmsvc_timeout has already been initialised. Unfortunately, there is no
no synchronisation between lockd() and lockd_up() to guarantee that this
is the case.
Fix is to move the initialisation of nlmsvc_timeout into lockd_create_svc
Fixes: 9a1b6bf818e74 ("LOCKD: Don't call utsname()->nodename...")
