Subject: [PATCH 4.9 44/51] fscache, cachefiles: remove redundant variable cache

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 31ffa563833576bd49a8bf53120568312755e6e2 ]

Variable 'cache' is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'cache' set but not used [-Wunused-but-set-variable]
