[PATCH][V2] btrfs-progs: allow autodetect_object_types() to handle link.

[Goffredo Baroncelli <kreijack@tiscali.it>]

From: Goffredo Baroncelli <kreijack@inwind.it>

The function autodetect_object_types() tries to detect the type of
btrfs object passed. If it is an "inode" type (e.g. file) this function
returns the type as "inode". If it is a block device, it return it as
"block device".
However it doesn't handle the case where the object passed is a link
to a block device (which could be a valid btrfs device). For example
LVM/DM creates link to block devices. In this case it should return
the type as "block device".

This patch replace the lstat() call with a stat().
