[PATCH] Bluetooth: btrtl: fix uninitialized scalar value

[Alonso Garrigues <agarrigues@riseup.net>]

There is a path where the variable is read uninitialized:
If the opcode switch case is RTL_PATCH_SECURITY_HEADER and key_id is
not set, the if statement condition immediately following the switch
checks an uninitialized rc
