simplify dmu_write_policy handling of pre-compressed buffers
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.
