I suppose the above two test_and_clear_bit() calls should be operating
on HCI_CONN_PARAM_REMOVAL_PEND and not HCI_CONN_MODE_CHANGE_PEND?

I don't think you need to initialize this here since it's
unconditionally set in the first LE addr type branch and only touched
again in the second LE branch. Actually do you even need this second
variable if you simply assign to conn when you look up the LE
connection?

Here you could then simply remove the "else" branch with a comment that
the conn is already looked up for LE addresses earlier in the function.
Not sure if that makes the code harder to follow though...
