Make sm-notify faster if there are no servers to notify

Dear Experts,

sm-notify was taking a long time while my laptop booted.  This was odd because I 
use NFS only rarely - via autofs - on that machine, and sm-notify actually has 
no-one to notify most of the time.  So I have patched it as follows.  Is this a 
legitimate thing to do?


diff -ur nfs-utils-1.1.3.orig/utils/statd/sm-notify.c nfs-utils-1.1.3/utils/statd/sm-notify.c
