[pve-devel] [PATCH manager v2 06/11] create: clear iothread on disable

[Thomas Lamprecht]

A user may set the `iothread` option and then change the bus type to
something which does not support it (sata, ide), while we disable
it the previously set value remains, which is confusing.
An user could think he coulkd trick the Wizard into using iothreads
for SATA/IDE but we just ignore the value in this case.

Set iothread to false in the case it gets disabled.
