USB: uas: Fix slave queue_depth not being set

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.
