If the input buffer does not have enough space to store the current xattr,
we set 'iter_ret' to -ERANGE and then do "break", but that only exits the
while loop over the xattrs in the current btrfs_dir_item, and then we
continue the btrfs_for_each_slot() iteration, which overwrites the value
of 'iter_ret' causing us to lose the error return value and proceed as if
the buffer has enough space.
Fix this by returning -ERANGE directly (the path is automatically freed)
instead of breaking from the while loop.
Fixes: 184b3d1900 ("btrfs: use btrfs_for_each_slot in btrfs_listxattr")
