stable inclusion from linux-4.19.155 commit b19305641e3c0c4b3758606b7bf6e57256094a1f
--------------------------------
[ Upstream commit 8e4c309f9f33b76c09daa02b796ef87918eee494 ]
ata_qc_complete_multiple() has to be called with the tags physically active, that is the hw tag is at bit 0. ap->qc_active has the same tag at bit ATA_TAG_INTERNAL instead, so call ata_qc_get_active() to fix that up. This is done in the vein of 8385d756e114 ("libata: Fix retrieving of active qcs").
