staging: lustre: osc: osc_extent_wait() shouldn't be interruptible

Otherwise it will hit the assertion at cl_lock.c:

 cl_lock.c:1967:discard_cb())
  ASSERTION( (!(page->cp_type == CPT_CACHEABLE) ||
  (!PageWriteback(cl_page_vmpage(env, page)))) ) failed:

This is because in osc_lock_flush() we have to make sure the IO
is finished before discarding the pages.
