Revert "sendf: make failf() use the mvsnprintf() return code"

Browse Source 
This reverts commit 74623551f306990e70c7c5515b88972005604a74.

Instead mark the function call with (void). Getting the return code and
using it instead triggered Coverity warning CID 1463596 because
snprintf() can return a negative value...

Closes #5441
