        src/sys/dev/ic: ld_nvme.c nvme.c nvmevar.h

Log Message:
refactor the locking code around DIOCGCACHE handling to be reusable
for other infrequent commands

it uses single condvar for simplicity, and uses it both when waiting
for ccb or command completion - this is fine, since usually there
will be just one such command qeueued anyway

use this to finally properly implement DIOCCACHESYNC - return only after
the command is confirmed as completed by the controller
