NTB: ntb_test: add parameter for doorbell bitmask
If the test attempts to clear doorbell bits that are invalid for the hardware, then the test will fail. Provide a parameter to specify the doorbell bits to clear. Set default doorbell bits that work for XEON. Signed-off-by: Allen Hubbe <Allen.Hubbe@dell.com> Acked-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
