autofs-5.1.4 - fix monotonic_elapsed
From: NeilBrown <neilb@suse.com>
When automount probes multiple hosts to find the one which
responds most quickly, it currently ignores the nanoseconds.
This often makes the cost "0", which makes weights ineffective.
The cause is that monotonic_elapsed() casts tv_nsec to a
double *after* dividing by 1 billion, rather than before.
With this change, weights become effective for choosing
between hosts which respond in under one second.
