Subject: [PATCH v1 1/1] sunrpc/cache: simplify qword_add

The commit 7572d3b29896 (lib/string_helpers.c: change semantics of
string_escape_mem) updates qword_add() to follow the changes in
lib/string_helpers.c. This patch simplifies the approach.

Andrew, I think this one can be folded in the mentioned commit by Rasmus.
