[PATCH] Btrfs-progs: Handle bad extent type case

[Frederic Weisbecker]

If we meet a bad extent type, find_updated_files is going
to print random things. Better warn the user about what
happens.

This fixes:

btrfs-list.c: Dans la fonction =C2=ABfind_updated_files=C2=BB :
btrfs-list.c:668: attention : =C2=ABdisk_offset=C2=BB may be used unini=
tialized in this function
btrfs-list.c:668: note: =C2=ABdisk_offset=C2=BB was declared here
btrfs-list.c:667: attention : =C2=ABdisk_start=C2=BB may be used uninit=
ialized in this function
btrfs-list.c:667: note: =C2=ABdisk_start=C2=BB was declared here
btrfs-list.c:666: attention : =C2=ABlen=C2=BB may be used uninitialized=
 in this function
btrfs-list.c:666: note: =C2=ABlen=C2=BB was declared here
make: *** [btrfs-list.o] Erreur 1
