Justin T. Gibbs cd6867d0d3 The following scenario would result in a bogus residual being reported 
if SCB Paging was enabled:

    disconnect with more data to transfer
    disconnected SCB gets paged out
    target reconnects so we page SCB back in
    target completes transfer so residual is 0
    target disconnects
    SCB gets reused but not paged out since the residual is 0 (optimization)
    target reconnects so we page the SCB back in
    we report a residual because of stale residual information.

The fix for this is to set a flag that forces the SCB to be paged back
up to the host if we page in an SCB with a residual
