Log:
  fix mips build breakage introduced in r216375: atomic_store_int doesn't exists
  
  1) 32-bit assignment are expected to always be atomic.
  2) Release/acquire memory barrier semantics doesn't seem to be needed here.
  So a simple assignment can be used.
  
  Remove unused port_set_counter() while here, it also used to mis-use
  atomic_set_int().
