usb-storage: unusual_devs entry to fix write-access regression for Seagate external drives

commit 113f6eb6d50cfa5e2a1cdcf1678b12661fa272ab upstream.

Kris Lindgren reports that without the NO_WP_DETECT flag, his Seagate
external disk drive fails all write accesses.  This regresssion dates
back approximately to the start of the 4.x kernel releases.
