firewire: sbp2: omit Scsi_Host lock from queuecommand
firewire-sbp2 already takes care for internal serialization where required (ORB list accesses), and it does not use cmd->serial_number internally. Hence it is safe to not grab the shost lock around queuecommand. While we are at housekeeping, drop a redundant struct member: sbp2_command_orb.done is set once in a hot path and dereferenced once in a hot path. We can as well dereference sbp2_command_orb.cmd->scsi_done instead. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
