Subject: [PATCH] btrfs: Move logging code in grub_btrfs_read_logical()
A portion of the logging code is moved outside of internal for(;;). The part
that is left inside is the one which depends on the internal for(;;) index.
This is a preparatory patch. The next one will refactor the code inside
the for(;;) into an another function.
