[PATCH 1/7] sched/deadline: Clear the defer params

[Andrea Righi <arighi@nvidia.com>]

From: Joel Fernandes <joelagnelf@nvidia.com>

The defer params were not cleared in __dl_clear_params. Clear them.

Without this is some of my test cases are flaking and the DL timer is
not starting correctly AFAICS.

Fixes: a110a81c52a9 ("sched/deadline: Deferrable dl server")
