surfaceflinger: odd hw rotation (90/270) patch for swapping width/height

This patch works in addition to the following commit
re-implementing ro.sf.hwrotation:
https://github.com/CyanogenMod/android_frameworks_native/commit/7d283431efffc4402cb1a6cacf5da64729c883bb

When using values of 90 and 270 for ro.sf.hwrotation the
LCD width and height also need to be swapped to display properly.
