USB: uas: Fix slave queue_depth not being set
Commit198de51dbc
("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. Cc: stable@vger.kernel.org Fixes:198de51dbc
