Bart Van Assche 8893cf6cb1 scsi: mpt3sas: Avoid sleeping in interrupt context
Commit 669f044170 ("scsi: srp_transport: Move queuecommand() wait code
to SCSI core") can make scsi_internal_device_block() sleep.  However,
the mpt3sas driver can call this function from an interrupt
handler. Hence add a second argument to scsi_internal_device_block()
that restores the old behavior of this function for the mpt3sas handler.

The call chain that triggered an "IRQ handler enabled interrupts"
complaint is as follows:

_base_interrupt()
-> _base_async_event()
   -> mpt3sas_scsih_event_callback()
      -> _scsih_check_topo_delete_events()
         -> _scsih_block_io_to_children_attached_directly()
            -> _scsih_block_io_device()
               -> _scsih_internal_device_block()
                  -> scsi_internal_device_block()
