usb: storage: add Genesys Logic 05e3:0749 to unusual_devs.h

Browse Source 
When test more than three Genesys Logic usb3 storages
(VID : PID = 0x05e3 : 0x0749) on rockchip platforms with
usb3 host port (e.g. rk3328/rk3399) at the same time,

test commands like this:
for dev in `ls /dev/sd?1 | sed -e 's,1$,,'`; do
	echo dd if=$dev of=/dev/null
	dd if=$dev of=/dev/null &
	sleep 1
done

The test fail with the following error log:
xhci-hcd xhci-hcd.9.auto: xHCI host not responding to stop endpoint command.
xhci-hcd xhci-hcd.9.auto: Assuming host is dying, halting host.
xhci-hcd xhci-hcd.9.auto: Host not halted after 16000 microseconds.
xhci-hcd xhci-hcd.9.auto: Non-responsive xHCI host is not halting.
xhci-hcd xhci-hcd.9.auto: Completing active URBs anyway.
xhci-hcd xhci-hcd.9.auto: HC died; cleaning up

This patch sets the max_sectors to 128 (64K) to workaround
this issue, and it doesn't affect the transmission rate.
