Ruiyu Ni 8bcbe587e7 MdeModulePkg/UsbKb: Don't access key codes when length is wrong
Per USB HID spec, the buffer holding key codes should be 8-byte
long.
Today's code assumes that the key codes buffer length is 8-byte
long and unconditionally accesses the key codes buffer.
It's incorrect.
The patch fixes the issue by returning Device Error when the
length is less than 8-byte.
