Description of problem:
'mount -a' fails to mount from more than one nfs server

Version-Release number of selected component (if applicable):
mount-2.11y-31.18.i386.rpm

How reproducible:
always

Steps to Reproduce:
1. Add mount points from two different nfs servers in /etc/fstab
2. Run 'mount -a'
  
Actual results:
"mount: RPC: Unable to receive; errno = Connection refused"

Expected results:
Should mount silently

Additional info:
I made a tcpdump and it looks like some port number confusion. The first server
accepts the mount, but additional servers reject the udp packages.

I can't reproduce it with mount-2.11y-31.11
