Bluetooth: Fix CIS host feature condition

Browse Source 
This fixes the condition for sending the LE Set Host Feature command.
The command is sent to indicate host support for Connected Isochronous
Streams in this case. It has been observed that the system could not
initialize BIS-only capable controllers because the controllers do not
support the command.

As per Core v6.2 | Vol 4, Part E, Table 3.1 the command shall be
supported if CIS Central or CIS Peripheral is supported; otherwise,
the command is optional.
