Also filter out fUnscaledLogicX being NaN

...which doesn't get filtered out by the following checks against the
pPosHelper->getLogicMin/MaxX() range, but leads to
-fsanitize=float-cast-overflow down the road when casting the propagated NaN in
double fDepth to sal_Int32 when loading xlsx/tdf80820-1.xlsx as obtained by
bin/get-bugzilla-attachments-by-mimetype (i.e., the attachment at
<https://bugs.documentfoundation.org/show_bug.cgi?id=80820#c0>):
