Alexander Motin 20f09eae42 ZIO: ZIO_STAGE_DDT_WRITE is a blocking stage
ddt_lookup() in zio_ddt_write() might require synchronous DDT ZAP
read.  Running it from interrupt taskq might lead to deadlock.
Inclusion of ZIO_STAGE_DDT_WRITE into ZIO_BLOCKING_STAGES should
hopefully fix that, even though I am not sure how I got there.
