    Revert "fs/fuse kio: add warning about jumbo chunks"
    
    This reverts commit 9896eef1f10b59018ef93f6c1cc41ce79ff2a1e1.
    
    After b9d027982dae ("fs/fuse kio: sync pcs_mds_sys_info struct")
    the patch being reverted is just incorrect because
    pcs_mds_sys_info.map_type has u8 type now and the patch being reverted
    checks 28th bit in info.sys.map_type.
    
    The proper check for jumbo chunks is implemented by another commit with
    the same subject: 6bd1a4548c09 ("fs/fuse kio: add warning about jumbo
    chunks")
