Subject: [PATCH] timedated: fix enable/disable reversal
Bug introduced in 984f1b1d1b. The state was flipped later,
but the enable/disable routine made use of the state to decide
what to do.
context_enable_ntp() and context_start_ntp() now get the desired
state directly, so the Context parameter can be removed.
(cherry picked from commit 81b843990297ad8c813c531fccd8da30bb715bd6)
