fuse: Set `max_pages` in `InitOut`

This field acts as a global upper bound on the size of any request so
read and write requests are truncated to fit this size even if
`max_readahead` and `max_write` are set to larger values.  Initialize
this field to the number of pages needed to fit the largest supported
requset size.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
