This fixes several instances of blk_status_t and bare errno ints being
mixed up, some of which are real bugs.

Reviewed-by: David Sterba <dsterba@suse.com>

The real bugs are lurking in the error cases, other than BLK_STS_OK that
is equivalent to the old return values.

Seems like blk_status_t conversion of raid56.c has been entirely
skipped, and maybe some of the changes brought by the btrfs pull. Thanks
for catching it. I'll prepare a pull request with this one for 4.13-rc7.
The other patch 2/7 is not that urgent and can wait.
