USB umass hard drive "failed to create xfers" when attaching

[Paul Goyette <paul%whooppee.com@localhost>]

With a 9.99.46 kernel built from sources dated 2020-02-07 16:26:35 UTC
I get the following errors when plugging in a USB hard drive:

umass0 at uhub1 port 2 configuration 1 interface 0
umass0: Western Digital (0x1058) Ext HDD 1021 (0x1021), rev 2.00/20.02, addr 32
umass0: using SCSI over Bulk-Only
umass0: autoconfiguration error: failed to create xfers

This worked correctly with a 9.99.42 kernel built from sources dated
2020-01-25 19:35:05 UTC

Anyone got any clues on how this got broke?  Or how to fix?
