Mark Harmstone a0f5689a68 btrfs: change btrfs_encoded_read() so that reading of extent is done by caller ...

[ Upstream commit 26efd44796 ]

Change the behaviour of btrfs_encoded_read() so that if it needs to read
an extent from disk, it leaves the extent and inode locked and returns
-EIOCBQUEUED. The caller is then responsible for doing the I/O via
btrfs_encoded_read_regular() and unlocking the extent and inode.
