illumos/illumos-gate@adaec86ad2

https://www.illumos.org/issues/8155
  When writing pre-compressed buffers, arc_write() requires that the compression
  algorithm used to compress the buffer matches the compression algorithm
  requested by the zio_prop_t, which is set by dmu_write_policy().
  This makes dmu_write_policy() and its callers a bit more complicated.
  We can simplify this by making arc_write() trust the caller to supply the type
  of pre-compressed buffer that it wants to write, and override the compression
  setting in the zio_prop_t.
