[v3,00/15] scsi: Add struct for args to execution functions

The following patches were made over Martin's scsi staging/next branch.
They add a struct that contains optinal arguments to the scsi_execute*
functions. This will be needed for the patches that allow the scsi
passthrough users to control retries because I'm adding a new optional
argument. I separated the 2 sets to make it easier to review and post.

v3:
- Init scsi_exec_args user's sshdr as "sshdr = sshdr ? : local".
- Use just one sense_len check and remove the scsi_execute_args wrapper.
- Just use one scsi_execute_cmd function and have it check if the args
  is NULL else use a local one.
- Pass exec_args by pointer.

v2:
- Fix RQF_QUIET use.
- Use the more standard way of passing in a struct for passing in
  the scsi_exec_args struct.
- Pass a struct scsi_exec_args instead of pointer and add another
  macro for the case the caller doesn't want to pass in a scsi_exec_args
  struct. Then remove the NULL args check in __scsi_execute.
