Bluetooth: Fix passing NULL to PTR_ERR
commit 266191aa8d14b84958aaeb5e96ee4e97839e3d87 upstream.
Passing NULL to PTR_ERR will result in 0 (success), also since the likes of
bt_skb_sendmsg does never return NULL it is safe to replace the instances of
IS_ERR_OR_NULL with IS_ERR when checking its return.
