2d5d264f99 tape/pool_writer: do not unwrap on channel send
if the reader thread is already gone here, we panic here, resulting in
a nondescript error message, so simply ignore/warn in that case and
return gracefully

73cef112eb tape: remove MediumType struct, which is only valid on IBM drives
HP drives do not return this information.

Note: This breaks format on WORM media, because we have not way
to detect WOREM media (how?).

71e83e1b1f tape/changer/sg_pt_changer: read whole descriptor size for each entry
Some changer seem to append more data than we expect, but correctly
annotates that size in the subheader.

For each descriptor entry, read as much as the size given in the
subheader (or until the end of the reader), else our position in
the reader is wrong for the next entry, and we will parse
incorrect data.
