[PATCH 11/20] Staging: hv: Get rid of the cdb_len from struct hv_storvsc_request

[K. Y. Srinivasan]

In preparation for consolidating all I/O request state, get rid of the
cdb_len field from struct hv_storvsc_request and instead use the
equivalent  state in struct vmscsi_request - cdb_length field.
