[SCSI] arcmsr: updates (1.20.00.15)

- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in
  arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell
  interrupt clearance is cached

- add conditional declaration for arcmsr_pci_error_detected() and
  arcmsr_pci_slot_reset

- check if the sg list member number exceeds arcmsr default limit in
  arcmsr_build_ccb()

- change the returned value type of arcmsr_build_ccb()from "void" to
  "int" returns FAILED in arcmsr_queue_command()

- modify arcmsr_drain_donequeue() to ignore unknown command and let
  kernel process command timeout.  This could handle IO request violating
  maximum segments, i.e.  Linux XFS over DM-CRYPT.  Thanks to Milan Broz's
  comments <mbroz@redhat.com>

- fix the release of dma memory for type B in arcmsr_free_ccb_pool()

- fix the arcmsr_polling_hbb_ccbdone()
