Btrfs bug fixes for 4.5

From: Filipe Manana <[email protected]>

Hi Chris,

Please consider the following fixes for the 4.5 merge window. Nothing outstanding, they are just the usual bug fixes (races, deadlocks, error paths, etc). These were all sent previously to the mailing list and rebased last week against your integration-4.4 branch (since there isn't any 4.5 integration branch yet).

Thanks.

The following changes since commit 1d3a5a82fe724c53c472a18a31fb0bbf33dfaba2:

Thanks Filipe, I'll get these in. I've been testing Omar's free space cache pretty hard, but I'll put his stuff on top of everything else just in case, and send out for -integration before xmas along with other queued items.
