Subject: [PATCH] lttng-tools: Fix live timer calculation error

There is an calculation error for live timer. Variable switch_timer_interval is
based on microsecond, and it is not right to assign switch_timer_interval mod
1000000 to var tv_nsec which is based on nanosecond.

Upstream-Status: Pending
