locking/seqlock: Simplify SEQCOUNT_LOCKNAME()

Browse source

1. Kill the "lockmember" argument. It is always s->lock plus
   __seqprop_##lockname##_sequence() already uses s->lock and
   ignores "lockmember".

2. Kill the "lock_acquire" argument. __seqprop_##lockname##_sequence()
   can use the same "lockbase" prefix for _lock and _unlock.

Apart from line numbers, gcc -E outputs the same code.
