    sbin/hammer: Remove redundant ioctl(GET_PSEUDOFS) call in getpfs()
    
    If scanpfsid() failed, it needs to try to open(2) the path whether
    it's a symlink or a file or a directory, but it needs not to call
    ioctl(GET_PSEUDOFS) which gets called right after this anyway.
    
    The error message "Cannot access PFS" is misleading too, because
    once scanpfsid() fails, the path isn't necessarily a PFS or a symlink
    to a PFS.
    
    Also note that calling this ioctl with -1 set to pfs.pfs_id is okay.
    In that case, the ioctl will try to detect the PFS id based on fd.
