Bug fix, submitted upstream

Add missing curly brackets that caused res_ninit() to be called
with non-zeroed state structure. In NetBSD, res_ninit() detects
the mistake and quickly calls res_ndestroy(), which will close file
descriptors based on the random data provided in the state structure.
The result at mine is sendmail going mute after the MAIL FROM
command.
