[Patch] netpoll: allow spaces in its parameter

[Amerigo Wang <amwang@redhat.com>]

It would be nice if we allow spaces in netconsole parameters,
otherwise we get weird results if there are spaces in it.

After this patch, we will allow things like:
 "netconsole= @192.168.0.1/eth0 , 66666@192.168.0.2/".
