nimble/ll: Fix max supported TX time

Browse Source 
Max TX time (regardless of PHY) is 17040us since this is maximum value
allowed by HCI commands and we should accept it. This does not mean we
will use whatever hosts requests since these are just suggestions and
we calculate actual supported and effective TX time taking into account
connection settings and other limitations from spec.
