MdeModulePkg/AbsPointer: Don't access key codes when length is wrong
Per USB HID spec, the buffer holding key codes should at least 3-byte
long.
Today's code assumes that the key codes buffer length is longer than
3-byte 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 3-byte.
