xfs: stop using xfs_trans_iget in the RT allocator

During mount we establish references to the RT inodes, which we keep for
the lifetime of the filesystem.  Instead of using xfs_trans_iget to grab
additional references when adding RT inodes to transactions use the
combination of xfs_ilock and xfs_trans_ijoin_ref, which archives the same
end result with less overhead.
