HV: remove vdev ops for sharing mode

Browse Source 
Remove vdev ops for sharing mode, directly call the corresponding functions
instead of calling the ops callbacks (indirectly)

Remove alloc_pci_vdev() and merge its code into init_vdev_for_pdev() to simplify code

Remove @pre for local variables

Change the return value from int32_t to void to comply with misra c and
add ASSERT in the functions (if necessary) to verify the assumptions for debug build:
 vmsi_init
 vmsix_init
 vmsi_deinit
 vmsix_deinit

Add @pre for vmsix_init_helper and make it a void function, use ASSERT to verify
the assumption for debug build.

Add ASSERT in get_sos_vm
