Move vhost.h to include/linux to allow vhost driver out-of-tree compilation. Currently, this cannot be done properly because the vhost header file is in driver/vhost. To distribute a new vhost driver before it is included in the kernel tree, we need to package it using kmod, dkms, ..., and to compile it out-of-tree using headers provided by the distribution's kernel development package.
