[PATCH 4.4 043/210] scsi: storvsc: fix SRB_STATUS_ABORTED handling

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>

commit ff06c5ffbcb4ffa542fb80c897be977956fafecc upstream.

Commit 3209f9d780d1 ("scsi: storvsc: Fix a bug in the handling of SRB
status flags") filtered SRB_STATUS_AUTOSENSE_VALID out effectively making
the (SRB_STATUS_ABORTED | SRB_STATUS_AUTOSENSE_VALID) case a dead code. The
logic from this branch (e.g. storvsc_device_scan() call) is still required,
fix the check.
