scsi: megaraid_sas: Block zero-length ATA VPD inquiry
A firmware bug was observed where ATA VPD inquiry commands with a
zero-length data payload were not handled and failed with a non-standard
status code of 0xf0.
Avoid sending ATA VPD inquiry commands without data payload by setting
the device no_vpd_size flag to 1. In addition, if the firmware returns a
status code of 0xf0, set scsi_cmnd->result to CHECK_CONDITION to
facilitate proper error handling.
