scsi: scsi_debug: Dynamically allocate sdebug_queued_cmd
Eventually we will drop the sdebug_queue struct as it is not really
required, so start with making the sdebug_queued_cmd dynamically allocated
for the lifetime of the scsi_cmnd in the driver.
As an interim measure, make sdebug_queued_cmd.sd_dp a pointer to struct
sdebug_defer. Also keep a value of the index allocated in
sdebug_queued_cmd.qc_arr in struct sdebug_queued_cmd.
To deal with an races in accessing the scsi cmnd allocated struct
sdebug_queued_cmd, add a spinlock for the scsi command in its priv area.
Races may be between scheduling a command for completion, aborting a
command, and the command actually completing and freeing the struct
sdebug_queued_cmd.
[mkp: typo fix]
