drivers/pci: Update the quirks for megaraid_sas adapter

This megaraid_sas adapter does have a valid pci vpd information.
Earlier commit 5bf1badcd02f ("pci: Limit VPD length for megaraid_sas
adapter") changed the vpd length to 0x80. This change fixed the panic.
However, we found some options of the lspci does not work very well if
it cannot find the valid vpd tag(Example command "lspci -s 10:00.0 -vv").
It displays the error message and exits right away. Setting the length
to 0 fixes the problem.
