 RSP <ffff903c6b783dc0>

As a part of host reset operation, driver will flushout all IOs outstanding
at driver level with "DID_RESET" result.  To find which are all commands
outstanding at the driver level, driver loops with smid starting from one
to HBA queue depth and calls mpt3sas_scsih_scsi_lookup_get() to get scmd as
shown below

 for (smid = 1; smid <= ioc->scsiio_depth; smid++) {
                scmd = mpt3sas_scsih_scsi_lookup_get(ioc, smid);
                if (!scmd)
                        continue;

But in mpt3sas_scsih_scsi_lookup_get() function, driver returns some scsi
cmnds which are not outstanding at the driver level (possibly request is
constructed at block layer since QUEUE_FLAG_QUIESCED is not set. Even if
driver uses scsi_block_requests and scsi_unblock_requests, issue still
persists as they will be just blocking further IO from scsi layer and not
from block layer) and these commands are flushed with DID_RESET host bytes
thus resulting into above kernel BUG.

This issue got introduced by commit dbec4c9040 ("scsi: mpt3sas: lockless
command submission").

To fix this issue, we have modified the mpt3sas_scsih_scsi_lookup_get() to
check for smid equals to zero (note: whenever any scsi cmnd is processing
at the driver level then smid for that scsi cmnd will be non-zero, always
it starts from one) before it returns the scmd pointer to the caller. If
smid is zero then this function returns scmd pointer as NULL and driver
won't flushout those scsi cmnds at driver level with DID_RESET host byte
thus this issue will not be observed.

[mkp: amended with updated fix from Sreekanth]
