mount.cifs: take extra care that mountpoint isn't changed during mount
It's possible to trick mount.cifs into mounting onto the wrong directory
by replacing the mountpoint with a symlink to a directory. mount.cifs
attempts to check the validity of the mountpoint, but there's still a
possible race between those checks and the mount(2) syscall.
To guard against this, chdir to the mountpoint very early, and only deal
with it as "." from then on out.
