4.9-stable review patch. If anyone has any objections, please let me know.

From: Icenowy Zheng icenowy@aosc.io
commit 0a99cc4b8ee83885ab9f097a3737d1ab28455ac0 upstream.
The SMI SM3350 USB-UFS bridge controller cannot handle long sense request correctly and will make the chip refuse to do read/write when requested long sense.
Add a bad sense quirk for it.
