Subject: fscache, cachefiles: remove redundant variable 'cache'
Git-commit: 31ffa563833576bd49a8bf53120568312755e6e2
Patch-mainline: v4.20-rc5
References: bsc#1210430

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]
