The VHE switch function calls __timer_enable_traps and
__timer_disable_traps which don't do anything on VHE systems.
Therefore, simply remove these calls from the VHE switch function and
make the functions non-conditional as they are now only called from the
non-VHE switch path.

Notes:
    Changes since v2:
     - Added comment explaining the timer enable/disable functions
       are for !VHE only.
