locking/csd-lock: Pack csd_lock_wait_toolong() state into a struct

csd_lock_wait_toolong() has some fields and they are being expanded now,
separate them into a structure, that can be easily digestible.

This simplify the function aslo, given the fields were passed by
reference, and the ts0/ts1 names say nothing about what the two
timestamps hold.

Pack them into struct csd_wait_state and name the timestamps for what
they store, ts_start and ts_report.  The local ts2 becomes ts_now.

Reporting a further timestamp, such as next patch, then costs a struct
member rather than another argument.

No functional change.
