dlls/user32/edit.c -- remove superflous check (RESEND)

[Gerald Pfeifer]

dwBufLen already indictes that this variable is of type DWORD and
thus always positive.  I also looked at the implementation of 
ImmGetCompositionStringW() and we do not seem to return a negative
value (such as -1).

Gerald

ChangeLog:
Remove superflous check in EDIT_GetCompositionStr().
