    Correct a bug in nfsrv_create() where a call to nfsrv_access() might
    be made holding the NFS server mutex.  To clean this up, introduce a
    version of the function, nfsrv_access_withgiant(), that expects the
    NFS server mutex to already have been dropped and Giant acquired.
    Wrap nfsrv_access() around this.  This permits callers to more
    efficiently check access if they're in a code block performing VFS
    operations, and can be substitited for the nfsrv_access() call that
    triggered this bug.
