Subject: [PATCH 2/3] btrfs-progs: receive: add debug messages when processing

 fallocate

Unlike for commands from the v1 stream, we have no debug messages logged

when processing fallocate commands, which makes it harder to debug issues.

So add log messages, when the log verbosity level is >= 3, for fallocate

commands, mentioning the value of all fields.
