ath10k: fix incorrect multicast/broadcast rate setting
Invalid rate code is sent to firmware when multicast rate value of 0 is
sent to driver indicating disabled case, causing broken mesh path.
so fix that.
Tested on QCA9984 with firmware 10.4-3.6.1-00827
Sven tested on IPQ4019 with 10.4-3.5.3-00057 and QCA9888 with 10.4-3.5.3-00053
(ath10k-firmware) and 10.4-3.6-00140 (linux-firmware 2018-12-16-211de167).
Fixes: cd93b83ad92 ("ath10k: support for multicast rate control")
