The check here guards the read below.
For `XimType_XIMStyles`, these are `num` of `CARD32` and for `XimType_XIMHotKeyTriggers`
these are `num` of `XIMTRIGGERKEY` ref[1] which is defined as 3 x `CARD32`.
(There are data after the `XIMTRIGGERKEY` according to the spec but they are not read by this
function and doesn't need to be checked.)
The old code here used the native datatype size instead of the wire protocol size causing
the check to always fail.
Also fix the size calculation for the header (size). It is 2 x CARD16 for both types
despite the unused `CARD16` for `XimType_XIMStyles`.
