[PATCH 1/5] Bluetooth: Remove superfluous call to hci_conn_check_pending()

[Jonas Dreßler]

The "pending connections" feature was originally introduced with commit
4c67bc74f016b0d360b8573e18969c0ff7926974 and
6bd57416127e92d35e6798925502c84e14a3a966 to handle controllers supporting
only a single connection request at a time. Later things were extended to
also cancel ongoing inquiries on connect() with commit
89e65975fea5c25706e8cc3a89f9f97b20fc45ad.

With commit a9de9248064bfc8eb0a183a6a951a4e7b5ca10a4,
hci_conn_check_pending() was introduced as a helper to consolidate a few
places where we check for pending connections (indicated by the
BT_CONNECT2 flag) and then try to connect.

This refactoring commit also snuck in two more calls to
hci_conn_check_pending():

- One is in the failure callback of hci_cs_inquiry(), this one probably
makes sense: If we send an "HCI Inquiry" command and then immediately
after a "Create Connection" command, the "Create Connection" command might
fail before the "HCI Inquiry" command, and then we want to retry the
"Create Connection" on failure of the "HCI Inquiry".

- The other added call to hci_conn_check_pending() is in the event handler
for the "Remote Name" event, this seems unrelated and is possibly a
copy-paste error, so remove that one.
