surfaceflinger: clean up captureScreen

dispScissor is never empty.  Remove the check and update the
comments so that the intention is clear.

It also becomes obvious that reqWidth/reqHeight is never zero when
we reach "// get screen geometry".  All code following the comment
is actually dead, which means we probably broke it since commit
06a58e22.

Bug: 113041375
Test: take screenshot, rotate screen, screencap
