USB: serial: io_edgeport: fix descriptor error handling

Make sure to detect short control-message transfers and log an error
when reading incomplete manufacturer and boot descriptors.

Note that the default all-zero descriptors will now be used after a
short transfer is detected instead of partially initialised ones.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
