    mount.nfs: Fix auto protocol negotiation

    Commit 71b807e1 introduce a regression that

    caused v3 not to be tried when v4 was not

    supported by the server during auto negation.

    A check of the type in nfs_nfs_version() was

    reverted back to only check for the "nfs4"

    string not the "nfs" string which fixed the

    problem.
