Alexander Motin 0aa99d33b5 Allow umass to use bigger transactions for USB 3.0 devices. It is less
important for USB 2.0 devices and some of them reported to have problems
with large transactions. But USB 3.0 benchmarks show that limited number
of transactions per second on USB makes impossible to reach high transfer
speeds without using bigger transactions.

On my tests this change allows to read up to 220MB/s from USB-attached SSD
(at block size of 256-512KB), comparing to only 113MB/s without it.
