[PATCH] btrfs: block-group: Make read_block_group_item return void

[Marcos Paulo de Souza <marcos@mpdesouza.com>]

From: Marcos Paulo de Souza <mpdesouza@suse.com>

Since it's inclusion on 9afc66498a0b
("btrfs: block-group: refactor how we read one block group item") this
function always returned 0, so there is no need to check for the
returned value.
