Jeffrey Hsu 34c54d9f74 Rewrite the SMP filedesc locking in knote_attach() in order to 
1.  eliminate unnecessary loop which frees and re-allocates
	the just allocated array
  2.  eliminate the newsize recomputation
  3.  eliminate unnecessary unlock and relock around free
  4.  correctly match the free with the malloc into M_KQUEUE instead of M_TEMP
  5.  eliminate conditional assignment of oldlist, which is equivalent to a
	simple assignment
  6.  eliminate the oldlist temporary variable completely
