[PATCH] Bluetooth: L2CAP: fix wrong identifier in __set_ack_timer()

[Pauli Virtanen <pav@iki.fi>]

__set_ack_timer(c) has chan->ack_timer instead of c->ack_timer like the
other macros.

Fix it to use the timer corresponding to the macro argument.  In current
code this is only called as __set_ack_timer(chan) so this has no runtime
impact.
