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.
