    nfs_commonsubs.c: Get rid of variable used as a constant
    
    The variable ncl_mbuf_mhlen is set to MHLEN and only
    used in one place.  This patch simply deletes it and
    replaces it with MHLEN.
    
    This patch should not affect semantics.
    
    Spotted while fixing cases that could do large
    NFSM_DISSECT() sizes.
    
    (cherry picked from commit 73551cd6eac29a6707c802c7d7fafcb560bf5e2b)
