seqlock: fix scoped_seqlock_read kernel-doc

Eliminate all kernel-doc warnings in seqlock.h:

- correct the macro to have "()" immediately following the macro name
- don't include the macro parameters in the short description (first line)
- make the parameter names in the comments match the actual macro
  parameter names.
- use "::" for the Example
