commit 871997bc9e423f05c7da7c9178e62dde5df2a7f8 upstream. The function uses a goto-based loop, which may lead to an earlier error getting discarded by a later iteration. Exit this ad-hoc loop when an error was encountered. The out-of-memory error path additionally fails to fill a structure field looked at by xen_blkbk_unmap_prepare() before inspecting the handle which does get properly set (to BLKBACK_INVALID_HANDLE). Since the earlier exiting from the ad-hoc loop requires the same field filling (invalidation) as that on the out-of-memory path, fold both paths. While doing so, drop the pr_alert(), as extra log messages aren't going to help the situation (the kernel will log oom conditions already anyway). This is XSA-365.
