Bluetooth: use inclusive language in SMP

Browse Source 
This patch replaces some non-inclusive terms based on the appropriate
language mapping table compiled by the Bluetooth SIG:
https://specificationrefs.bluetooth.com/language-mapping/Appropriate_Language_Mapping_Table.pdf

Specifically, these terms are replaced:
master -> initiator
slave  -> responder
