    Revert "df: remove the unused fstype var"
    
    This reverts commit 647f70e6bf4213f3a892277fcafe2c36d81aa3a5.
    
    fstype is used in a call to build_iovec_argf() in this branch, and the
    reverted commit didn't remove the variable, just its initialization.
    
    This is a direct commit to stable/12.
    
    Reported by:    GCC -Wmaybe-uninitialized
