Subject: [PATCH] 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.
