[dpdk-dev] [PATCH] devtools: fix symbol check for filename with space

[Thomas Monjalon <thomas@monjalon.net>]

If the patch filename or the temporary file path have a space
in their name, the script check-symbol-change.sh does not work.
The variables for the filenames must be enclosed in quotes
in order to preserve spaces.

Fixes: 4bec48184e33 ("devtools: add checks for ABI symbol addition")
