Prevent premature resetting of quickswitch mode

Previously, whenever a user returned to the same
rotation that they had started quickswitch in,
we were sending sysui the reset flag(-1) indicating
that quickstep was complete instead of sending
the rotation of the device the user was in.

This was intentional and it worked, however we now
always send the active rotation while the user
is in a quickswitch session because sysui needs
to show the fake home handle for immersive apps,
which can occur in any rotation. This state is
distinct from not being in quickswitch at all, in
which no fake handles are shown.
