[PATCH 5/9] btrfs: move logging code in grub_btrfs_read_logical()

[Goffredo Baroncelli]

A portion of the logging code is moved outside a for(;;). The part that is
left inside is the one which depends by the for(;;) index.
This is a preparatory patch: in the next one it will be possible to refactor
the code inside the for(;;) in an another function.
