[LTP] [PATCH] netns: remove accumulated errmesg assignment

[Monson S. <js...@re...>]

Valuable $errmesg wasn't initialized at beginning, when bash option
"nounset" is set, statement like errmesg="$errmesg XXXXXX" will cause
bash unbound variable error.

Furthermore, $errmesg will be echoed every time it is assigned, so
there is no need for accumulated assignment.
