cifs: add a "nosharesock" mount option to force new sockets to server to be created
Some servers set max_vcs to 1 and actually do enforce that limit. Add a
new mount option to work around this behavior that forces a mount
request to open a new socket to the server instead of reusing an
existing one.
I'd prefer to come up with a solution that doesn't require this, so
consider this a debug patch that you can use to determine whether this
is the real problem.
