[PATCH v2 1/1] sunrpc/cache: simplify qword_add

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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.
Changelog v2:
- add missed curly braces (grr... I have them in initial comment)
