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.
