[PATCH] usb: usb-storage: No additional quirks need to be added to the ECD819-SU3 optical drive.

[ccc194101@163.com]

From: Chen Changcheng <chenchangcheng@kylinos.cn>

The optical drive of ECD819-SU3 has the same vid and pid as INIC-3069,
as follows:
T:  Bus=02 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#=  3 Spd=5000 MxCh= 0
D:  Ver= 3.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 9 #Cfgs=  1
P:  Vendor=13fd ProdID=3940 Rev= 3.10
S:  Manufacturer=HL-DT-ST
S:  Product= DVD+-RW GT80N
S:  SerialNumber=423349524E4E38303338323439202020
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=144mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=02 Prot=50 Driver=usb-storage
E:  Ad=83(I) Atr=02(Bulk) MxPS=1024 Ivl=0ms
E:  Ad=0a(O) Atr=02(Bulk) MxPS=1024 Ivl=0ms

This will result in the optical drive device also adding
the quirks of US_FL_NO_ATA_1X. When performing an erase operation,
it will fail, and the reason for the failure is as follows:
