RT4347: Fix GCC unused-value warnings with HOST_c2l()
The HOST_c2l() macro assigns the value to the specified variable, but also
evaluates to the same value. Which we ignore, triggering a warning.
To fix this, just cast it to void like we did in commit 08e553644
("Fix some clang warnings.") for a bunch of other instances.
