Fix ICE on conditional expression between DFP and non-DFP float (PR c/71601).
A conditional expression between DFP and non-DFP floating-point
produces an ICE. This patch fixes this by making
build_conditional_expr return early when c_common_type produces an
error.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
