b9d13664ab Bluetooth: Create protocol-specific outgoing ACL buffer pools 
With this split we get better control of the buffer sizes and counts.
We also anyway will need a fragments pool so a simple generic ACL_OUT
pool doesn't make sense anymore. The related Kconfig options for that
have been removed.
