We make a minor simplification in the way we define
RADIO_PDU_LEN_MAX in Nordic nRF LE radio driver; as
nRF51 SoC series is the only series where the LL PDU
max length representation is limited to a 5-bit field,
we simplify the conditional preprocessor expression,
to avoid having to list all nRF5x SoCs with PDU LEN
MAX is represented by an 8-bit integer field.
In addition, we modify the preprocessor conditional,
that compiles in the CCM support for 8-bit length field,
PDUs to be an #ifndef CONFIG_SOC_SERIES_NRF51X, instead
of #ifdef CONFIG_SOC_COMPATIBLE_NRF52X; this will
simplify the expression when adding nRF53X series
support.

LLL context.
Signed-off-by: Vinayak Kariappa Chettimada <vich@nordicsemi.no>
When more than one simultaneous connections are active,
transmitting data packets to peer, a termination causes
host to use the flushed pending number of completed packets
count for other active connections. This is on reception
of HCI disconnection complete event. But the controller has
not yet released any of the pending enqueued Tx buffers
which was happening after the disconnection event was
dispatched to HCI layer.
The fix here is to dispatch the disconnection complete event
from the LLL context after pending Tx buffers have been
flushed and the buffers get returned to Tx pool in the ULL
context. This way buffers are in the Tx pool before host
get to process the disconnection complete event.
