time: Add missing colons for parameter documentation of time64_to_tm()

Address these kernel-doc warnings:

 kernel/time/timeconv.c:79: warning: Function parameter or member
 'totalsecs' not described in 'time64_to_tm'
 kernel/time/timeconv.c:79: warning: Function parameter or member
 'offset' not described in 'time64_to_tm'
 kernel/time/timeconv.c:79: warning: Function parameter or member
 'result' not described in 'time64_to_tm'

The parameters are described but lack colons after the parameter name.
