David Sterba 33f58a0480 btrfs: initialize last_extent_end to fix -Wmaybe-uninitialized warning in extent_fiemap() ...

There's a warning (probably on some older compiler version):

fs/btrfs/fiemap.c: warning: 'last_extent_end' may be used uninitialized in this function [-Wmaybe-uninitialized]:  => 822:19

Initialize the variable to 0 although it's not necessary as it's either
properly set or not used after an error. The called function is in the
same file so this is a false alert but we want to fix all
-Wmaybe-uninitialized reports.
