Subject: [PATCH 1/2] i2c: stm32: fix slot id after introduction of host-notify support

Commit 68302245720a ("i2c: stm32f7: Add SMBus Host-Notify protocol support")
added a new slot specific for handling host-notify however failed
to update the previous slot ID leading to having the 7bit address
only slot with the wrong number.
