Subject[PATCH v5 4/6] erofs: make the size of read data stored in buffer_ofs
Date
Since now xattr_iter structures have been unified, make the size of the
read data stored in buffer_ofs. Don't bother reusing buffer_size for
this use, which may be confusing.

This is in preparation for the following further cleanup.
