[XFS] sort out opening and closing of the block devices
Currently closing the rt/log block device is done in the wrong spot, and
far too early. So revampt it:
- xfs_blkdev_put moved out of xfs_free_buftarg into the caller so that
it is done after tearing down the buftarg completely.
- call to xfs_unmountfs_close moved from xfs_mountfs into caller so
that it's done after tearing down the filesystem completely.
- xfs_unmountfs_close is renamed to xfs_close_devices and made static
in xfs_super.c
- opening of the block devices is split into a helper xfs_open_devices
that is symetric in use to xfs_close_devices
- xfs_unmountfs can now lose struct cred
- error handling around device opening sanitized in xfs_fs_fill_super
