Module Name:    src
Committed By:   jdolecek
Date:           Fri Jun 23 22:11:13 UTC 2017

Modified Files:
        src/sys/dev/ata [jdolecek-ncq]: wd.c

Log Message:
change wd_standby() to remove the ata_channel_start() call - the purpose
of that particular command is to make the drive idle

fix locking bug in wddetach() exposed by calling ata_channel_start()
in wd_standby() - move wd_standby() call out of the section protected
by drive mutex, to avoid lock against itself should it need to get
the lock

change wd_flushcache() to only call ata_channel_start() when called from
the ioctl; particularly, don't call it when suspending, closing, or on shutdown
