Modified Files:
	syssrc/sys/dev/ata: ata.c atavar.h
	syssrc/sys/dev/ic: wdc.c

Log Message:
In wdc_exec_command(), for data commands, read the status register after
the data transfer. This is mandatory for data out commands (although none are
used for now), and not forbiddend for data in commands. Also record if we
did transfers any data.
May solve kern/16159 by making the probe more robust in face of fake identify.
