Bluetooth: increment TX timestamping tskey always for stream sockets
Documentation/networking/timestamping.rst implies TX timestamping OPT_ID
tskey increments for each sendmsg. In practice: TCP socket increments
it for all sendmsg, timestamping on or off, but UDP only when
timestamping is on. The user-visible counter resets when OPT_ID is
turned on, so difference can be seen only if timestamping is enabled for
some packets only (eg. via SO_TIMESTAMPING CMSG).
Fix BT sockets to work in the same way: stream sockets increment tskey
for all sendmsg (seqpacket already increment for timestamped only).
Fixes: 134f4b39df7b ("Bluetooth: add support for skb TX SND/COMPLETION timestamping")
