Bluetooth: use configured params for ext adv [STREAMEIGHT-4746]

commit 5cbd3eb upstream When the extended advertisement feature is enabled, a hardcoded min and max interval of 0x8000 is used. This patch fixes this issue by using the configured min/max value. This was validated by setting min/max in main.conf and making sure the right setting is applied: < HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036) plen 25 torvalds#93 [hci0] 10.953011 … Min advertising interval: 181.250 msec (0x0122) Max advertising interval: 181.250 msec (0x0122) … Signed-off-by: Alain Michaud <[email protected]> Reviewed-by: Abhishek Pandit-Subedi <[email protected]> Reviewed-by: Daniel Winkler <[email protected]> Signed-off-by: Marcel Holtmann <[email protected]> Signed-off-by: Michal Dzik <[email protected]>
