timekeeping: Use proper seqcount initializer
tk_core.seq is initialized open coded, but that misses to initialize the lockdep map when lockdep is enabled. Lockdep splats involving tk_core seq consequently lack a name and are hard to read. Use the proper initializer which takes care of the lockdep map initialization.
