File 0002-fix-concurrent-and-nfs.patch of Package ebtables

Our customer reported a following issue:
If '--concurrent' was passed to ebtables command behind other arguments,
'--concurrent' will not take effect sometimes; for a simple example,
ebtables -L --concurrent. This is becuase the handling of '--concurrent'
is implemented in a passing-order-dependent way.

Fixed this problem as Pablo Neira Ayuso suggested by simply spewing
an error like following:
./ebtables-legacy -L --concurrent
Please put the --concurrent option first.
