[PATCH] devtool: fix falsely reporting from checkpatch

[WanRenyong]

When executes the check_packed_attributes function in checkpatch,
if __rte_packed_begin or __rte_packed_end appear in the context
of a patch file, there may be a situation where the counts of
__rte_packed_begin and __rte_packed_end do not match, causing
checkpatch to return a failure.
This patch fixes this issue by only counting the lines in the
patch file that start with a + and include either
__rte_packed_begin or __rte_packed_end.
