remove some unused variables

Fixes:
  device/generic/goldfish-opengl/android-emu/android/base/ring_buffer.c:
  426:23: warning: unused variable 'yield_backoff_us' [-Wunused-const-variable]
  427:23: warning: unused variable 'sleep_backoff_us' [-Wunused-const-variable]
  435:14: warning: unused variable 'start_us' [-Wunused-variable]
  436:14: warning: unused variable 'curr_wait_us' [-Wunused-variable]
  478:14: warning: unused variable 'step_shift' [-Wunused-variable]

which in turn makes ring_buffer_curr_us() an unused function and thus can be deleted.

Test: builds, and:
  git grep 'yield_backoff_us|sleep_backoff_us|start_us|curr_wait_us|step_shift'
  finds nothing
