The io requests to the NVMe device gets broken down to 64k requests

I would like to ask Canonical to cherry pick the followng patch:

commit 5f009d3f8e6685fe8c6215082c1696a08b411220

    block: Initialize max_dev_sectors to 0

    The new queue limit is not used by the majority of block drivers, and
    should be initialized to 0 for the driver's requested settings to be used.
