Increase maximum queue size to be compatible with crosvm.
Since crosvm commit 2d8dc7154
("devices: vhost-user: vmm: remove QueueSizes"), the crosvm frontend now uses a queue size of 32768 with all backend devices.
Per the crosvm developers' reading of the spec, "a vhost-user backend must accept any valid VHOST_USER_SET_VRING_NUM
from the frontend", but virtiofsd hardcodes a queue size of 1024, and does not implement . (Prior to that changed, it worked.)VHOST_USER_SET_VRING_NUM
to allow the frontend to tell it what queue size to use, so it's not compatible with crosvm versions that include this change
