[RFC][PATCH 2/6][usercr] Remove flags parameter to cr_checkpoint()

Subject: [RFC][PATCH 2/6][usercr] Remove flags parameter to cr_checkpoint()

For consistency with cr_restart(), remove 'flags' parameter to cr_checkpoint().
Given that we pass in the 'struct cr_checkpoint_args' the flags parameter is
anyway redundant.
