[PATCH 1/4] wifi: mwifiex: remove unnecessary queue empty check

[Sascha Hauer]

Since 7bff9c974e1a ("mwifiex: send firmware initialization commands
synchronously") all initialization commands are sent synchronously which
means the command queue is empty when mwifiex_sta_init_cmd() returns. No
need to check for entries in the command code then, so remove the check.

Add a WARN_ON() just in case there is something wrong with the
reasoning.
