Bluetooth: Fix incorrect LE CoC PDU length restriction based on HCI MTU
Bluetooth: Fix incorrect LE CoC PDU length restriction based on HCI MTU

The l2cap_create_le_flowctl_pdu() function that l2cap_segment_le_sdu()
calls is perfectly capable of doing packet fragmentation if given bigger
PDUs than the HCI buffers allow. Forcing the PDU length based on the HCI
MTU (conn->mtu) would therefore needlessly strict operation on hardware
with limited LE buffers (e.g. both Intel and Broadcom seem to have this
set to just 27 bytes).

This patch removes the restriction and makes it possible to send PDUs of
the full length that the remote MPS value allows.
