block: virtual-storage: Fix build for Linux v6.9

Browse Source 
In Linux v6.9-rc1, the function blk_mq_init_queue() was renamed
blk_mq_alloc_queue() and the arguments passed to the function were
updated. Add a test to conftest to detect if the function
blk_mq_alloc_queue() is present and update the virtual-storage driver
accordingly.
