[SCSI] mpt2sas: Fix for dead lock occurring between host_lock and sas_device_lock
Fix for dead lock occurring between host_lock and sas_device_lock.
The deadlock is between two spin locks, between the shost->host_lock
and driver ioc->sas_device_lock.
The fix is to rearrange the code in the FW/Driver device removal
handshake so the ioc->sas_device_lock is not occurring when the
shost->host_lock is taken.
[jejb: zero initialise sas_address to fix spurious compiler warning]
