Maxim Levitsky cfd4e36352 scsi: fix device removal race vs IO restart callback on resume
There is (mostly theoretical) race between removal of a scsi device and
scsi_dma_restart_bh.

It used to be easier to hit this race prior to my / Paulo's patch series
that added rcu to scsi bus device handling code, but IMHO this race
should still be possible to hit, at least in theory.

Buglink: https://bugzilla.redhat.com/show_bug.cgi?id=1854811

Fix it anyway with a patch that was proposed by Paulo in the above bugzilla.
