Colin Ian King f5e8e21586 Bluetooth: btrtl: fix incorrect skb allocation failure check ...

Currently the check for a failed bt_skb_alloc allocation is incorrectly
checking using IS_ERR and this can lead to a null pointer dereference. Fix
this by checking for a null pointer return using the !skb idiom.
