linux_usbfs: Wait until all URBs have been reaped before freeing them

Prior to this change, the URBs allocated for an individual transfer were
freed when the last URB in the transfer was reaped. Normally this causes
no issues because URBs are reaped in the order they were submitted. If
the device is disconnected while multiple URBs are queued, these URBs
may be reaped in an order that does not match that of submission.

Change the logic to free the URBs when all the URBs of a transfer have
been reaped rather than the last one. While in here, improve some debug
messages.

Closes #607
