[PATCH] btrfs-progs: fix send-test build

[Eric Sandeen <sandeen@redhat.com>]

btrfs_read_and_process_send_stream() recently changed its prototype;
this gets it building again.  0 means "do not honor the <end cmd>"
which was the previous default, before

2bfac02 Btrfs-progs: btrfs-receive optionally honors the end-cmd

I . . . guess 0 is sane for this test?  If not maybe Stefan can
speak up.
