Pull SCSI fixes from James Bottomley:
"Two small fixes.
One prevents timeouts on mpt3sas when trying to use the secure erase
protocol which causes the erase protocol to be aborted. The second is
a regression in a prior fix which causes all commands to abort during
PCI extended error recovery, which is incorrect because PCI EEH is
independent from what's happening on the FC transport"

scsi: qla2xxx: do not abort all commands in the adapter during EEH recovery
