wcn36xx: Move hal_buf allocation to devm_kmalloc in probe
[ Upstream commit ef48667 ] Right now wcn->hal_buf is allocated in wcn36xx_start(). This is a problem since we should have setup all of the buffers we required by the time ieee80211_register_hw() is called. struct ieee80211_ops callbacks may run prior to mac_start() and therefore wcn->hal_buf must be initialized. This is easily remediated by moving the allocation to probe() taking the opportunity to tidy up freeing memory by using devm_kmalloc().
