Pull scsi fixes from Martin Petersen:
"These two commits were in a separate postmerge branch due to a
dependency on changes merged for 5.4 in the block tree.
They fix two issues in the intersection of the request cleanup changes
from block (
b7e9e1fb7a92) and the request batching changes
(
8930a6c20791) that were made to SCSI during the 5.4 cycle"
