MdeModulePkg/UsbMass: Fix USB key write failure 

Commit e59db6a732
* MdeModulePkg/UsbMass: Merge UsbBoot(Read|Write)Blocks(16)
introduces a bug that causes writing to USB key always fails.

When that patch is verified, only reading was verified.

The root cause is when the writing operation is performed,
the data direction EfiUsbDataIn is wrongly used. Instead, it
should be EfiUsbDataOut.
