Subject: vhost: remove an incorrect assert
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cb4b4fde82b064472c13fb9d983ca36a70e560aa;p=qemu.git

vhost: remove an incorrect assert

The 'to' can go negative when the first region gets removed
(it gets incremented by to 0 immediately afterward), which
makes the assertion fail. Nothing breaks if
to < 0 here so just remove the assert.
