Subject: [PATCH] zsmalloc: remove unused variable

The variable 'entry' is no longer used and the compiler rightly
complains that it should be removed.

../mm/zsmalloc.c: In function ‘zs_pool_stat_create’:
../mm/zsmalloc.c:648:17: warning: unused variable ‘entry’ [-Wunused-variable]
  struct dentry *entry;
                 ^~~~~

Rework to remove the unused variable.

Fixes: 4268509a36a7 ("zsmalloc: no need to check return value of debugfs_create functions")
