[PULL 09/14] vmdk: Clean up bdrv_open_child() return value check

[Kevin Wolf <kwolf@redhat.com>]

From: Dmitry Frolov <frolov@swemel.ru>

bdrv_open_child() may return NULL.
Usually return value is checked for this function.
Check for return value is more reliable.

Fixes: 24bc15d1f6 ("vmdk: Use BdrvChild instead of BDS for references to extents")
