be2net: Free/delete pmacs (in be_clear()) only if they exist

Browse source

During suspend-resume and lancer error recovery we will cleanup and
re-initialize the resources through be_clear() and be_setup() respectively.
During re-initialisation in be_setup(), if be_get_config() fails, we'll again
call be_clear() which will cause a NULL pointer dereference as adapter->pmac_id is
already freed.
