        src/sys/dev/scsipi: atapiconf.c cd.c scsi_base.c scsiconf.c
            scsipi_base.c sd.c ss.c st.c

Log Message:
The atapibus detach path did hold the channel mutex while calling into autoconf,
which would trigger a panic when unplugging a USB ATAPI CDROM.

Align detach code for scsibus and atapibus to fix this.

Also avoid races when detaching devices by replacing callout_stop with
callout_halt.
