[dpdk-dev] [PATCH 2/2] devtools: fix forbidden token

[David Marchand]

An expression with a space is split by the awk script resulting in
false positive for any patch matching any of the two part of the
expression.
Fix this by using [[:space:]].

Fixes: 43e73483a4b8 ("devtools: forbid variable declaration inside for")
