Subject: [PATCH 2/2] Bluetooth: mgmt: remove useless NULL check in add_ext_adv_params_complete()

Remove the cmd pointer NULL check in add_ext_adv_params_complete()
because it occurs earlier in add_ext_adv_params(). This check is
also unnecessary because the pointer is dereferenced just before it.

Found by Linux Verification Center (linuxtesting.org) with Svace.
