In short, place the following before your \usepackage for fontspec and/or unicode-math:

\usepackage{expl3}
\ifdefined\suppressfontnotfounderror
 \expandafter\let\csname xetex_suppressfontnotfounderror:D\endcsname
   \suppressfontnotfounderror
\else
 \expandafter\let\csname xetex_suppressfontnotfounderror:D\endcsname
 \luatexsuppressfontnotfounderror
\fi

Once the expl3 packages (specifically l3kernel) have been updated you can remove it.

Thanks to the folks on the tex-live list for this information.

Good Luck,
