usb: cdc-acm: stop dropping tx buffers
The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!). This patch removes them:
- The write_ready flag ... if an URB and buffer were found,
they can (and should!) always be used.
- TX path acm_wb_is_used() ... used when the buffer was just
allocated, so that check is pointless.
Also fix a won't-yet-matter leak of a write buffer on a disconnect path.
