Add #ifndef MAX_QUEUES to change MAX_QUEUES at compile time if needed.
Change MAX_QUEUES from 512 to 128 to reduce the number of hugepages
required by the vhost-switch program.
To change MAX_QUEUES add '-D MAX_QUEUES=512' to the EXTRA_CFLAGS variable,
before building the application.
Changes in v3:
Added #ifndef MAX_QUEUES line before #define MAX_QUEUES 128
Changes in v2:
remove comment added before #define MAX_QUEUES in v1 patch.
