        src/sys/dev/ata [jdolecek-ncq]: TODO.ncq ata.c ata_wdc.c atavar.h
        src/sys/dev/ic [jdolecek-ncq]: mvsata.c wdc.c wdcvar.h

        src/sys/dev/scsipi [jdolecek-ncq]: atapi_wdc.c

Log Message:
remove all logic around ATACH_IRQ_WAIT and channel-global ch_error/ch_status,
so that there is less hidden state shared by commands; primary intent is
to make the NCQ and non-NCQ paths more similar, and remove possibility
of incorrect handling for the NCQ commands

tested both disk and ATAPI - piixide(4) on QEMU, and siisata(4),
ahcisata(4), mvsata(4) on real hw
