btrfs: qgroup: cleanup the unused srcroot from btrfs_qgroup_inherit

Since commit 3a84d5417df6 ("btrfs: root->fs_info cleanup, add fs_info
convenience variables"), the srcroot is no longer used to get
fs_info::nodesize.  In fact, it can be dropped after commit 27dec8dc8d80
("btrfs: use nodesize everywhere, kill leafsize").
