Nikolay Borisov 04bc461062 Reduce stack usage of dmu_recv_stream function 
The receive_writer_arg and receive_arg structures become large
when ZFS is compiled with debugging enabled. This results in
gcc throwing an error about excessive stack usage:

  module/zfs/dmu_send.c: In function ‘dmu_recv_stream’:
  module/zfs/dmu_send.c:2502:1: error: the frame size of 1256 bytes is
  larger than 1024 bytes [-Werror=frame-larger-than=]

Fix this by allocating those functions on the heap, rather than
on the stack.

With patch:    dmu_send.c:2350:1:dmu_recv_stream 240 static
Without patch: dmu_send.c:2350:1:dmu_recv_stream 1336 static
