Or just drop the backport, since it adds annotation, while the original
was fixing existing annotation.

__raw_write_seqcount_begin() called in 5.4-rt try_write_seqlock() is
not annotated, while write_seqcount_begin() called by the 5.9-rt
version leads to the broken annotation that the original then fixed.
