Subject: [PATCH] qemu: alias: Generate 'qomName' of disk with useraliases

Commit fb64e176f4f forgot to delete the check that short-circuits the
|
|
disk alias creation if the alias is already present. The side effect
|
|
of this is that the creation qomName which is necessary to be able to
|
|
refer to disk frontends when -blockdev is used was skipped when user
|
|
aliases are used.
|
|
|
|
Fix it by deleting the check. Also prevent any potential memory leaks
|
|
from calling this function repeatedly by creating the qomName only when
|
|
it's not present.
