Subject: [PATCH] disc: DiscRead carries SCSI status/sense

Fix extract_scsi_context() and Error::scsi_sense() to handle Error::DiscRead
in addition to Error::ScsiError, so is_marginal_read() works for DiscRead
errors and disc::copy() can properly route MEDIUM ERROR as a marginal
(bad sector) instead of bailing.

Closes: freemkv-private#20260427
