    nimble/host: Truncate data in ble_eatt_tx
    
    Data packets sent over eatt chan weren't correctly truncated.
    Data packet is now adjusted to peer device's MTU for the channel.
    Fixes various GATT/SR test cases that verify support for Read Long
    Characteristic Value Requests, Multiple Read Characteristic Value
    Requests etc.
