Wang Yugui f0c2bb0057 btrfs-progs: send: sync splice buf size with kernel when proto 2 
When 'btrfs send --proto 2', the max buffer in kernel is changed from
BTRFS_SEND_BUF_SIZE_V1(SZ_64K) to (SZ_16K + BTRFS_MAX_COMPRESSED).

The performance is improved when we use the same buffer size in
btrfs-progs:

without this patch:  57.96s
with this patch:     48.44s

Bigger buffer size 512K was tested too, but it did not improve protocol
2 over 1 significantly.
