From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The error status err is initialized as zero and then being checked
several times to see if it is less than zero even when it has not
been updated. Since these checks are redundant we can remove these
as well as err and the error exit label err_exit.
Detected by CoverityScan, CID#1398313 and CID#1398306 ("Logically
dead code")
