xfs: simplify xfs_buf_get / xfs_buf_read interfaces
Currently the low-level buffer cache interfaces are highly confusing
as we have a _flags variant of each that does actually respect the
flags, and one without _flags which has a flags argument that gets
ignored and overriden with a default set. Given that very few places
use the default arguments get rid of the duplication and convert all
callers to pass the flags explicitly. Also remove the now confusing
_flags postfix.
