[PATCH] tcg: drop qemu_cpu_is_self() in tlb_flush_by_mmuidx[_async_work]

[Igor Mammedov]

QEMU will crash with following debug enabled
  # define DEBUG_TLB_GATE 1
  # define DEBUG_TLB_LOG_GATE 1
due to [1] introduced assert and as it happenstlb_flush_by_mmuidx[_async_work]
functions are called not only from vcpu thread but also from reset handler
that is called from main thread at cpu realize time when vcpu is already
created
  x86_cpu_new -> ... ->
      x86_cpu_realizefn -> cpu_reset -> ... ->
          tcg_cpu_reset_hold

drop assert to fix crash.
