imm: Don't crash in ImmConfigureIME when dwMode is IME_CONFIG_REGISTERWORD and lpData is NULL (resend)

[Aric Stewart]

Humm, according to MSDN:

"If dwMode is set to IME_CONFIG_REGISTERWORD, this parameter must 
indicate a REGISTERWORD structure."


If windows does not crash in this case, then maybe it would involve 
checking for the non-presence of the parameter and returning the correct 
error.

So it looks like your fix is not quite correct.
