[PATCH] btrfs-progs: btrfs_setup_chunk_tree_and_device_map: Return -EIO on error.

[PATCH] btrfs-progs: btrfs_setup_chunk_tree_and_device_map: Return -EIO on error.

[chandan]

As a result of a successful call to btrfs_read_sys_array(), the 'ret'
variable is already set to 0. Hence the function would return 0 even
if the call to read_tree_block() fails.
