The specification says when PRACT is 1 and metadata size is 8, the
controller generates and appends protection information to the end
of the logical block data, this looks like only valid for extended
LBA format, but from real test with different drives, for separate
metadata case, some drives require host allocated buffer while some
not, for metadata bigger than 8 bytes cases, they all need host
buffer, so we allocate this buffer in host for all cases here.
