rtlwifi: Fix leak of skb when processing C2H_BT_INFO

With commit 0a9f8f0a1b ("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.
