[libvirt] [PATCHv2 2/2] virBitmapParse: Don't shadow errors



A few of the callers of virBitmapParse shadow the returned error.
---

Notes:
    I'm kind of worried that we are making some error messages
    worse compared to what they were before. If you don't like
    the way this will turn out, I'll prepare a inverse fix
    where all callers will be fixed to report proper errors
    and virBitmapParse will remain silent.
