[RFC PATCH 3/3] btrfs-progs: receive: make quiet really quiet

[Anand Jain <anand.jain@oracle.com>]

A message is still being printed even when the receive option --quiet
is specified, this patch fixes it.

before:
---- btrfs receive -q -f /tmp/t /btrfs1 -----
At snapshot ss3
---- btrfs receive -f /tmp/t /btrfs1 -----
At snapshot ss3

after:
---- btrfs receive -q -f /tmp/t /btrfs1 -----
---- btrfs receive -f /tmp/t /btrfs1 -----
At snapshot ss3

Signed-off-by: Anand Jain <anand.jain@oracle.com>

fstests doesn't use --quiet option, so all test cases should remain
unaffected with this change.
