Subject: [Backport 94182167ec73] exfat: fix possible memory leak in

 exfat_find()

'es' is malloced from exfat_get_dentry_set() in exfat_find() and should

be freed before leaving from the error handling cases, otherwise it will

cause memory leak.

Fixes: 5f2aa075070c ("exfat: add inode operations")
