USB: uas: Fix slave queue_depth not being set
commit 593224ea77b1ca842f45cf76f4deeef44dfbacd1 upstream.
Commit 198de51dbc34 ("USB: uas: Limit qdepth at the scsi-host level")
removed the scsi_change_queue_depth() call from uas_slave_configure()
assuming that the slave would inherit the host's queue_depth, which
that commit sets to the same value.
This is incorrect, without the scsi_change_queue_depth() call the slave's
queue_depth defaults to 1, introducing a performance regression.
This commit restores the call, fixing the performance regression.
Fixes: 198de51dbc34 ("USB: uas: Limit qdepth at the scsi-host level")
