EX-9108 obdclass: disable T10PI guard from disk when decompressing

When server handles chunk unaligned read, we need to read
the chunk from disk and decompress the raw data.
This means we should not use the guard tags from the storage,
as they only match the raw data.
Disable the guard from disk and the T10PI checksum will be
recalculated later using decompressed data.
