Fix: lttng-ctl: _handle can be NULL

lttng_destroy_session_no_wait does not care for the returned handle
and passes a NULL _handle.

This leads to an immediate LTTNG_ERR_INVALID failure on
lttng_destroy_session_no_wait calls.

lttng_destroy_session_ext already performs a null check on _handle
before assigning it to transfer ownership of the handle.

Fixes #1241
