[libvirt] [PATCH v2] qemu: command: align disk serial check to schema

[Nikolay Shirokovskiy]

Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated
in 85d15b51 where ability to add serial was added.

Diff from v1:

* fix xml2argv disk serial test to use all valid chars

Looks like there is no existing infrastructure to test every invalid character.
