Subject: [PATCH net-next v2 1/4] be2net: remove be_cmd_get_profile_config_mbox/mccq() variants

From: Vasundhara Volam <vasundhara.volam@...lex.com>

Fix be_cmd_get_profile_cmd() to use be_cmd_notify_wait() routine,
which uses MBOX if MCCQ has not been created. Doing this reduces
code duplication; we don't need the _mbox/_mccq() variants anymore.
