ovl: using posix_acl_xattr_size() to get size instead of posix_acl_to_xattr()

Browse Source 
There is no functional change but it seems better to get size by calling
posix_acl_xattr_size() instead of calling posix_acl_to_xattr() with
NULL buffer argument. Additionally, remove unnecessary assignments.
