seqcount: Rename write_seqcount_barrier()
[ Upstream commit a7c6f571ff51cc77d90dd54968f7c5c938c43998 ] I'll shortly be introducing another seqcount primitive that's useful to provide ordering semantics and would like to use the write_seqcount_barrier() name for that. Seeing how there's only one user of the current primitive, lets rename it to invalidate, as that appears what its doing. While there, employ lockdep_assert_held() instead of assert_spin_locked() to not generate debug code for regular kernels.
