This patchset fixes a qgroup bug when using with inode_cache mount option.
The bug reminds us that the design of separate
btrfs_qgroup_prepare_account_extents() is a bad practice especially the
safest timing is to call prepare just before btrfs_qgroup_account_extents().
So the patchset will cleanup btrfs_qgroup_prepare_account_extents() to
avoid further similar bugs.
And add a quick exit for non-fs extents for qgroup, mainly to reduce the
noise of qgroup trace events.
