Commit 56f3d383f3 ("scsi: scsi_devinfo: Add TRY_VPD_PAGES to HITACHI
OPEN-V blacklist entry") modified some Hitachi entries:
HITACHI is always supporting VPD pages, even though it's claiming to
support SCSI Revision 3 only.
The same should have been done also for HP-rebranded.

Commit 627511e3e6 ("[SCSI] scsi_devinfo: update Hitachi entries (v2)")
modified some Hitachi entries:
Four models, OPEN-/DF400/DF500/DISK-SUBSYSTEM, can handle
REPORT_LUN, and the BLIST_REPORTLUN2 flag needs to be set. And DF600
doesn't require any flags because it returns ANSI 03h (SPC).
The same should have been done also for HP counterparts.

When driver is loaded in Target/Dual mode, it creates QPair to support
MQ and allocates resources for each QPair. This Qpair initialization is
delayed until the FW personality is changed to Dual/Target mode by
issuing chip reset. At the time of chip reset firmware is re-initilized
in correct personality all the QPairs are initialized by sending
MBC_INITIALIZE_MULTIQ (001Fh).
This patch fixes memory leak by adding check to issue
MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the
flag is set for initiator mode, and clean up QPair resources correctly
during the driver unload. This MBX does not need to be issued for
Target/Dual mode because chip reset will reset ISP.

since commit 28a0bc4120 ("scsi: sd: Implement blacklist option for

checking whether bit 31 is set in the return value is not sufficient to
tell the difference between an error code and a flags value.
