rtlwifi: Fix leak of skb when processing C2H_BT_INFO
commit 8cfa272b0d321160ebb5b45073e39ef0a6ad73f2 upstream.
With commit 0a9f8f0a1ba9 ("rtlwifi: fix btmpinfo timeout while processing
C2H_BT_INFO"), calling rtl_c2hcmd_enqueue() with rtl_c2h_fast_cmd() true,
the routine returns without freeing that skb, thereby leaking it.
This issue has been discussed at https://github.com/lwfinger/rtlwifi_new/issues/401
and the fix tested there.
