[PATCH] ath11k: mask out vht beamforming if a fixed rate is set

[John Crispin]

From: Ritesh Singh <ritesi@codeaurora.org>

After setting a fixed vht-rate we see a FW assert if a STA tries to
(re)assoc with the mu_bfee cap set. This patch masks out the capability
bits if a fixed rate is set.

John's s-o-b missing. Also no magic numbers, please. Isn't there a proper
define for 0x3?
