system/posix-acl: fix acl inode assignment in posix_acl_readdirp_cbk
If an entry includes no ACL returned via dictionary, it is possible
to skip down to acl_set without updating acl_access and/or
acl_default. If either are set from the previous iteration, the
unrelated ACLs are set to the current entry. Use a single set of
pointers to ensure that valid ACLs are always set.
