In preparation for consolidating all I/O request state, get rid of the type field from struct hv_storvsc_request and instead use the equivalent state in struct vmscsi_request - data_in field. In the current code there is a call to zero out the struct vstor_packet in stor_vsc_on_io_request(). So, to be able to directly set the state in the vstor_packet in blkvsc_drv.c and storvsc_drv.c, get rid of the call to zero out the packet in stor_vsc_on_io_request() and instead allocate the request structure that has been zeroed out.

Now that vmbus_driver is a pci driver, cleanup the irq allocation mess by using the standard irq allocation mechanisms. Note that this patch generates an error when the checkpatch script is run because of the IRQF_SAMPLE_RANDOM flag used in request_irq() function. This interrupt may be the only external event this VM will get and consequently if this flag (IRQF_SAMPLE_RANDOM) is not specified, experimentally we have shown that the entropy in the VM will very very low.
