[PATCH -tip v1 1/3] Documentation: seqlock: s/LOCKTYPE/LOCKNAME/g

[Ahmed S. Darwish]

Sequence counters with an associated write serialization lock are called
seqcount_LOCKNAME_t. Fix the documentation accordingly.

While at it, remove a paragraph that inappropriately discussed a
seqlock.h implementation detail.

Fixes: 6dd699b13d53 ("seqlock: seqcount_LOCKNAME_t: Standardize naming convention")
