Peter Krempa 65eb7c85a3 block/qcow2: Move bitmap reopen into bdrv_reopen_commit_post 
The bitmap code requires writing the 'file' child when the qcow2 driver
is reopened in read-write mode.

If the 'file' child is being reopened due to a permissions change, the
modification is commited yet when qcow2_reopen_commit is called. This
means that any attempt to write the 'file' child will end with EBADFD
as the original fd was already closed.

Moving bitmap reopening to the new callback which is called after
permission modifications are commited fixes this as the file descriptor
will be replaced with the correct one.

The above problem manifests itself when reopening 'qcow2' format layer
which uses a 'file-posix' file child which was opened with the
'auto-read-only' property set.
