39f2f080b3 usb-storage: always print quirks
Right now quirks are printed only when the are manually overriden with
the module parameters. It's not so useful to remind the user that his
parameters are correctly applied; what is useful is to print out the
quirks the user is not aware are being applied.

So let's do the smart thing and print the quirks when they are present.

Increase the bulk-out buffer size to avoid any regression in throughput
after replacing the old writing scheme which used dynamic buffers (e.g.

256b has been determined to be a good choice for several drivers
including ftdi_sio which used to have a more or less identical write
implementation.

Kill custom read and write implementations (dynamically allocated write

Note that I chose to remove the stat module parameter which was supposed
to keep count of the amount of data sent and received, but which has
been broken for three years (since b308e74d9c
"USB: visor driver adapted to new tty buffering" -- bytes_in was
incorrectly updated and was thus always reported as 0).
