[PATCH] staging: rtl8192 Check for Null return from dev_skb_alloc

From: Nicholas Krause
Date: Thu Jun 19 2014 - 16:18:30 EST


Checks for Null return from dev_skb_alloc if it returns Null,
fw_download returns false. Otherwise it returns true.Also
removed rt_status due to returning true of false directly.
